OK - that clarifies what will go wrong in a way so that even I can understand it ;-)

How about if we just don't care that much about breaking this when people switch to another major version of Perl ??? We must assume -some- intelligence on the part of people that install Perl & ports that depend on Perl. We do that already in asking them to configure some ports & moving files around. So how about a warning in Perl5 that switching Perl5 version will break future re-builds of the ports they have that depend on a version of Perl5 ??? & telling them which ports will break upon re-building ??? Otherwise, I do think that we should focus on supporting just one single version of Perl5. That discussion was brought up earlier in the thread.

Presently, it hinders people in using any other version of Perl unless they are willing to do what I've done : have a local repo with pathces with all of the troubles that can lead to. -- Bjarne D Mathiesen København N ; Danmark ; Europa ---------------------------------------------------------------------- denne besked er skrevet i et totalt M$-frit miljø MacOS X 10.7.3 Lion ; 2.8GHz Intel Core i7 ; 16GB 1067MHz DDR3 _______________________________________________ macports-dev mailing list macports-dev@lists.macosforge.org http://lists.macosforge.org/mailman/listinfo.cgi/macports-dev
