To explicitly name the perl binary, use the command
"make install PERLNAME=myperl".
+Building perl from source requires an ANSI compliant C-Compiler.
+A minimum of C89 is required. Some features available in C99 will
+be probed for and used when found. The perl build process does not
+rely on anything more than C89.
+
These options, and many more, are explained in further detail below.
If you have problems, corrections, or questions, please see

list of locally installed modules. Also see CPAN::autobundle for one
way to make a "bundle" of your currently installed modules.

"-Duserelocatableinc" is that everything is relocated. The initial
install is done to the original configured prefix.
+This option is not compatible with the building of a shared libperl

+rpath that points at the libperl.so, that cannot be relocated.

=head2 Site-wide Policy settings
After Configure runs, it stores a number of common site-wide "policy"
To disable certain extensions so that they are not built, use the
-Dnoextensions=... and -Donlyextensions=... options. They both accept

+a space-separated list of extensions, such as C<IPC/SysV>. The extensions
+listed in
C<noextensions> are removed from the list of extensions to build, while
the C<onlyextensions> is rather more severe and builds only the listed
extensions. The latter should be used with extreme caution since
SCO prior to 3.2.4 may be missing dbmclose(). An upgrade to 3.2.4
that includes libdbm.nfs (which includes dbmclose()) may be available.
+=item error: too few arguments to function 'dbmclose'

+Building ODBM_File on some (Open)SUSE distributions might run into this

If you see such a message during the building of an extension, but
by hand to see if it makes any difference. If individual tests
bomb, you can run them by hand, e.g.,

Another way to get more detailed information about failed tests and
individual subtests is to cd to the t directory and run
=head1 Coexistence with earlier versions of perl 5
-Perl 5.11 is not binary compatible with earlier versions of Perl.
+Perl 5.12 is not binary compatible with earlier versions of Perl.
In other words, you will have to recompile your XS modules.
In general, you can usually safely upgrade from one version of Perl (e.g.
libraries after 5.6.0, but not for executables. TODO?) One convenient
way to do this is by using a separate prefix for each version, such as
- sh Configure -Dprefix=/opt/perl5.11.4
+ sh Configure -Dprefix=/opt/perl5.13.1
-and adding /opt/perl5.11.4/bin to the shell PATH variable. Such users
