=head1 DESCRIPTION
-The latest Perl release (5.8.8 as of this writing) builds without changes
-under Mac OS X. Under 10.3 "Panther" and newer OS versions, all self-tests
-pass, and all standard features are supported.
+The latest Perl release (5.12.3 as of this writing) builds without changes
+under all versions of Mac OS X from 10.3 "Panther" onwards.
+
+In order to build your own version of Perl you will need 'make'
+this is part of the Apples developer tools (you only need the 'unix tools'),
+usually supplied with Mac OS install DVDs. You do not need the latest
+version of Xcode (which is now charged for) in order to install make.
Earlier Mac OS X releases (10.2 "Jaguar" and older) did not include a
completely thread-safe libc, so threading is not fully supported. Also,
-Aldflags="-arch i686 -arch ppc -Wl,-syslibroot,$SDK" \
-de
+In Leopard (MacOSX 10.5.6 at the time of this writing) you must use the 10.5 SDK:
+
+ export SDK=/Developer/SDKs/MacOSX10.5.sdk
+
+You can use the same compiler flags you would use with the 10.4u SDK.
+
Keep in mind that these compiler and linker settings will also be used when
building CPAN modules. For XS modules to be compiled as a universal binary, any
libraries it links to must also be universal binaries. The system libraries that
Apple includes with the 10.4u SDK are all universal, but user-installed libraries
may need to be re-installed as universal binaries.
+=head2 64-bit PPC support
+
+Follow the instructions in F<INSTALL> to build perl with support for 64-bit
+integers (C<use64bitint>) or both 64-bit integers and 64-bit addressing
+(C<use64bitall>). In the latter case, the resulting binary will run only
+on G5-based hosts.
+
+Support for 64-bit addressing is experimental: some aspects of Perl may be
+omitted or buggy. Note the messages output by F<Configure> for further
+information. Please use C<perlbug> to submit a problem report in the
+event that you encounter difficulties.
+
+When building 64-bit modules, it is your responsibility to ensure that linked
+external libraries and frameworks provide 64-bit support: if they do not,
+module building may appear to succeed, but attempts to use the module will
+result in run-time dynamic linking errors, and subsequent test failures.
+You can use C<file> to discover the architectures supported by a library:
+
+ $ file libgdbm.3.0.0.dylib
+ libgdbm.3.0.0.dylib: Mach-O fat file with 2 architectures
+ libgdbm.3.0.0.dylib (for architecture ppc): Mach-O dynamically linked shared library ppc
+ libgdbm.3.0.0.dylib (for architecture ppc64): Mach-O 64-bit dynamically linked shared library ppc64
+
+Note that this issue precludes the building of many Macintosh-specific CPAN
+modules (C<Mac::*>), as the required Apple frameworks do not provide PPC64
+support. Similarly, downloads from Fink or Darwinports are unlikely to provide
+64-bit support; the libraries must be rebuilt from source with the appropriate
+compiler and linker flags. For further information, see Apple's
+I<64-Bit Transition Guide> at
+L<http://developer.apple.com/documentation/Darwin/Conceptual/64bitPorting/index.html>.

=head2 libperl and Prebinding
Mac OS X ships with a dynamically-loaded libperl, but the default for
for pre-binding.
You can override the default and build a shared libperl if you wish
-(S<Configure ... -Duseshrlib>), but the load time on pre-10.4 OS
+(S<Configure ... -Duseshrplib>), but the load time on pre-10.4 OS
releases will be greater than either the static library, or Apple's
pre-bound dynamic library.
Starting with Tiger (Mac OS X 10.4), Apple shipped broken locale files for
the eu_ES locale (Basque-Spain). In previous releases of Perl, this resulted in
-failures in the C<lib/locale> test. These failures have been supressed
+failures in the F<lib/locale> test. These failures have been suppressed
in the current release of Perl by making the test ignore the broken locale.
If you need to use the eu_ES locale, you should contact Apple support.
-=head2 MacPerl
-
-Quite a bit has been written about MacPerl, the Perl distribution for
-"Classic MacOS" - that is, versions 9 and earlier of MacOS. Because it
-runs in environment that's very different from that of UNIX, many things
-are done differently in MacPerl. Modules are installed using a different
-procedure, Perl itself is built differently, path names are different,
-etc.
-
-From the perspective of a Perl programmer, Mac OS X is more like a
-traditional UNIX than Classic MacOS. If you find documentation that
-refers to a special procedure that's needed for MacOS that's drastically
-different from the instructions provided for UNIX, the MacOS
-instructions are quite often intended for MacPerl on Classic MacOS. In
-that case, the correct procedure on Mac OS X is usually to follow the
-UNIX instructions, rather than the MacPerl instructions.

-=head2 Carbon
-
-MacPerl ships with a number of modules that are used to access the
-classic MacOS toolbox. Many of these modules have been updated to use
-Mac OS X's newer "Carbon" toolbox, and are available from CPAN in the
-"Mac::Carbon" module.

=head2 Cocoa
After this you can either copy Perl from your operating system media
(you will need at least the /System/Library/Perl and /usr/bin/perl),
or rebuild Perl from the source code with C<Configure -Dprefix=/usr
--Dusershrplib> NOTE: the C<-Dprefix=/usr> to replace the system Perl
+-Duseshrplib> NOTE: the C<-Dprefix=/usr> to replace the system Perl
works much better with Perl 5.8.1 and later, in Perl 5.8.0 the
settings were not quite right.
