Thats why we could use a debian-perl list. In the perl thread from
March 12, Z. Hull makes a plan that satisfies some people (Joey H. and Chip
S.) . But I forgot too, and had to dig it out. (Not too hard because it was
The idea was to keep the current perl and perl5.005 at the same
time. The perl5.004 does not use versioned directories. And the new
modules depend on perl5.005.
I do see a problem though. What about scripts ? Scripts should all
point to /usr/bin/perl, but we need simultaneous versions of perl. I guess
/etc/alternatives can only point to one perl at a time. But some scripts
will need different versions depending on which modules they are using. I am
confused, maybe I don't understand something.
Does it make sense to set the unversioned perl library path to be
last in @INC in perl5.005, so any modules that were not
upgraded will be found there ?
btw. Here is an interesting bit from A. Cox from this week on lsb-discuss
Im very concerned we don't try and mandate perl too much. Every tiny
subrelease of perl breaks something different, and there is no formal
grammar for perl to reference against that I can find.
Perl is a bigger nightmare than libc variance
