in reply to Professional development with Perl - how it's done?

Usually I create an installation package of perl and the modules I use:

But I didn't really solve the problem with OS independend installations for the whole perl version with modules.

If I need to upgrade a module, a testsuite for my code helps me finding errors. I can't trust module authors not to change interfaces any more (recently happened to me in Readonly v1.01: Readonly \$scalar => 20 to v1.03: Readonly $scalar => 20, or Mail::Mailer, where the option 'test' was replaced with 'testfile')

The only time I had to change a CPAN module (needed to change the Makefile of DBD::SQLite from UTF8 to ANSI because of an old Tk version (8.04?) which couldn't handle UTF8 correctly) I additionally saved the whole perl installation within a version control system. Since the only target was windows, it worked well.

Best regards,
perl -e "s>>*F>e=>y)\*martinF)stronat)=>print,print v8."
