use Perl

opl-perl => wtf? well, it should stand for opt perl perl :-)

• Perl 5.10.0-22 for Lenny
• can be found in /opt/perl/bin/perl
• /usr/share/t/* experiment

The goal is to have Perl+modules from Squeeze (Debian/testing) available in Lenny (Debian/stable) whithout touching the system /usr/bin/perl.

Ingredients:

• 1 Debian Lenny
• working internet connection
• piece of curiosity
• ~5 minutes

Procedure:

gpg --recv-key F80BD927
gpg --fingerprint --list-key F80BD927
# check
# pub 1024D/F80BD927 2008-09-02 [expires: 2018-08-31]
# Key fingerprint = 9F84 0B8D 193E 2052 9343 A470 0B43 A050 F80B D927
gpg --armor --export F80BD927 | sudo apt-key add -

Comments:

Did I say it's experiment? Or a proof that it's possible and a playground. :-) For example checkout the /usr/share/t/ folder after instalation. I've setup debhelper to copy the whole content of t/ folder of each package there. It seems that it's not a good idea as many tests are depending on having files outside the t/ folder, looking for t/some.pm or are looking for .pm files as for example everywhere used pod.t test. Besides there is a Module::Build with dependecies so it's a solid base to install all the rest of the CPAN via CPAN shell ;-)
