   6 # (If you are trying to port this package to a machine without sh,
   7 # I would suggest you have a look at the prototypical config_h.SH file
   8 # and edit it to reflect your system. Some packages may include samples
   9 # of config.h for certain machines, so you might look for one of those.)
  10 #
  11 # Yes, you may rip this off to use in other distribution packages. This
  12 # script belongs to the public domain and cannot be copyrighted.
  13 #
  14 # (Note: this Configure script was generated automatically. Rather than
  15 # working with this copy of Configure, you may wish to get metaconfig.
  16 # The dist-3.0 package (which contains metaconfig) was posted in
  17 # comp.sources.misc and is available on CPAN under authors/id/RAM so
  18 # you may fetch it yourself from your nearest archive site.)
  19 #
  20 #
  21 # Though this script was generated by metaconfig, it is OK to send
  22 # patches against it. It's up to the Configure pumpkin to backport
  23 # the patch to the metaunits if it is accepted.
  24 # See Porting/pumpkin.pod for more information on metaconfig.

2158 This installation shell script will examine your system and ask you questions
2159 to determine how the perl5 package should be installed. If you get
2160 stuck on a question, you may use a ! shell escape to start a subshell or
2161 execute a command.  Many of the questions will have default answers in square
2162 brackets; typing carriage return will give you the default.
2163
2164 On some of the questions which ask for file or directory names you are allowed
2165 to use the ~name construct to specify the login directory belonging to "name",
2166 even if you don't have a shell which knows about that.  Questions where this is
2167 allowed will be marked "(~name ok)".

2174
2175 The prompter used in this script allows you to use shell variables and
2176 backticks in your answers.  You may use $1, $2, etc...  to refer to the words
2177 in the default answer, as if the default line was a set of arguments given to a
2178 script shell.  This means you may also use $* to repeat the whole default line,
2179 so you do not have to re-type everything to add something to the default.
2180
2181 Everytime there is a substitution, you will have to confirm.  If there is an
2182 error (e.g. an unmatched backtick), the default answer will remain unchanged
2183 and you will be prompted again.
2184
2185 If you are in a hurry, you may run 'Configure -d'.  This will bypass nearly all
2186 the questions and use the computed defaults (or the previous answers if there
2187 was already a config.sh file). Type 'Configure -h' for a list of options.
2188 You may also start interactively and then answer '& -d' at any prompt to turn
2189 on the non-interactive behaviour for the remainder of the execution.

2195 Much effort has been expended to ensure that this shell script will run on any
2196 Unix system.  If despite that it blows up on yours, your best bet is to edit
2197 Configure and run it again.  If you can't run Configure for some reason,
2198 you'll have to generate a config.sh file by hand.  Whatever problems you
2199 have, let me (perlbug@perl.org) know how I blew it.
2200
2201 This installation script affects things in two ways:
2202
2203 1) it may do direct variable substitutions on some of the files included
2204    in this kit.
2205 2) it builds a config.h file for inclusion in C programs.  You may edit
2206    any of these files as the need arises after running this script.
2207
2208 If you make a mistake on a question, there is no easy way to back up to it
2209 currently.  The easiest thing to do is to edit config.sh and rerun all the SH
2210 files.  Configure will offer to let you do this before it runs the SH files.

4350     Your gcc has not been compiled for the exact release of

4352
4353     In general it is a good idea to keep gcc synchronized with
4354     the operating system because otherwise serious problems
4355     may ensue when trying to compile software, like Perl.
4356
4357     I'm trying to be optimistic here, though, and will continue.
4358     If later during the configuration and build icky compilation
4359     problems appear (headerfile conflicts being the most common
4360     manifestation), I suggest reinstalling the gcc to match
