+IMPORTANT NOTE: 5.005_53 and later releases do not export unadorned
+global symbols anymore. This means most CPAN modules probably won't
+build under this release without adding '-DPERL_POLLUTE' to ccflags
+in config.sh. This is not the default because we want the modules
+to get fixed *before* the 5.006 release. pod/perldelta.pod contains
+additional notes about this.

+=head1 WARNING: This version requires a compiler that supports ANSI C.
+
+If you find that your C compiler is not ANSI-capable, try obtaining
+GCC, available from GNU mirrors worldwide (e.g. ftp://ftp.gnu.org/pub/gnu).
+Another alternative may be to use a tool like C<ansi2knr> to convert the
+sources back to K&R style, but there is no guarantee this route will get
+you anywhere, since the prototypes are not the only ANSI features used
+in the Perl sources. C<ansi2knr> is usually found as part of the freely
+available C<Ghostscript> distribution. Another similar tool is
+C<unprotoize>, distributed with GCC. Since C<unprotoize> requires GCC to
+run, you may have to run it on a platform where GCC is available, and move
+the sources back to the platform without GCC.
+
+If you succeed in automatically converting the sources to a K&R compatible
+form, be sure to email perlbug@perl.com to let us know the steps you
+followed. This will enable us to officially support this option.
=head1 Space Requirements
into a directory typically found along a user's PATH, or in another
obvious and convenient place.
+You can use "Configure -Uinstallusrbinperl" which causes installperl
+to skip installing perl also as /usr/bin/perl.
+
By default, Configure will compile perl to use dynamic loading if
your system supports it. If you want to force perl to be compiled
statically, you can either choose this when Configure prompts you or
If you need to install perl on many identical systems, it is
convenient to compile it once and create an archive that can be
-installed on multiple systems. Here's one way to do that:
+installed on multiple systems. Suppose, for example, that you want to
+create an archive that can be installed in /opt/perl.
+Here's one way to do that:
# Set up config.over to install perl into a different directory,
# e.g. /tmp/perl5 (see previous part).
- sh Configure -des
+ sh Configure -Dprefix=/opt/perl -des
make
make test
- make install
+ make install # This will install everything into /tmp/perl5.
cd /tmp/perl5
- # Edit $archlib/Config.pm to change all the

# install* variables back to reflect where everything will
- # really be installed.
- # Edit any of the scripts in $scriptdir to have the correct
+ # really be installed. (That is, change /tmp/perl5 to /opt/perl
+ # everywhere in those files.)
+ # Check the scripts in $scriptdir to make sure they have the correct
# #!/wherever/perl line.
tar cvf ../perl5-archive.tar .
# Then, on each machine where you want to install perl,

tar xvf perl5-archive.tar
