Build A Custom PERL Installation

If you want to build a PERL installation that is separate from your standard PERL, you can compile one, complete with CPAN support. Just follow these steps:

1. mkdir /custom/perl/
2. cd /custom/perl/
3. curl -O http://www.cpan.org/src/perl-5.12.3.tar.gz
4. mkdir perl-5_12_3
5. gunzip perl-5.12.3.tar.gz
6. tar -xf perl-5.12.3.tar
7. cd perl-5.12.3
8. ./Configure -d -Dprefix=/custom/perl/perl-5_12_3
9. make
10. make test
11. make install
12. /custom/perl/perl-5_12_3/bin/perl -v
13. /custom/perl/perl-5_12_3/bin/perl -e ‘print “hello world.\n”;’
14. /custom/perl/perl-5_12_3/bin/perl -MCPAN -e shell
    • Auto configure as much as possible. Step 15 will edit it.
15. Edit /custom/perl/perl-5_12_3/lib/5.12.3/CPAN/Config.pm
    • Change the following paths:
    • ‘cpan_home’ => q[/custom/perl/perl-5_12_3/cpan/],
    • ‘build_dir’ => q[/custom/perl/perl-5_12_3/cpan/build],
    • ‘histfile’ => q[/custom/perl/perl-5_12_3/cpan/histfile],
    • ‘keep_source_where’ => q[/custom/perl/perl-5_12_3/cpan/sources],
    • ”prefs_dir’ => q[/custom/perl/perl-5_12_3/cpan/prefs],
    • ”urllist’ => [q[ftp://my.cpan.mirror/pub/cpan/]],
16. Run CPAN and install Bundle::CPAN Bundle::LWP and any required packages
17. tar -cvf /custom/perl/custom-perl5.12.13.tar /custom/perl/perl-5_12_3/*
18. gzip /custom/perl/custom-perl5.12.13.tar
19. Ship custom-perl5.12.13.tar.gz out to your matching architectures or mount it on a shared NAS.
20. Call it with #!/custom/perl/perl-5_12_3/bin/perl
