I _think_ I understand where Fink is coming from and I wouldn't break it for the world; I depend upon it. And I'm less sure I understand where CPAN is too although I have gotten some conflicting answers from it today, that's for sure. But the quandary is that CPAN contains MUCH more than what Fink will ever supply and so I need to use both, in a non-destructive and hopefully seamless way. My earlier testing today told me that this wasn't as simple as using both at the same time. Not unexpected now that I see what's what in hindsight. So, what I did was trash (moved aside actually) my .cpan directory and started over. During the fresh startup of cpan I selected a verbose config process and selected the "local::lib" option among other things. I think this is the key option for what I want to do. This created a perl5 directory in my $HOME with lib, lib/perl5, bin, and man under it. It also added some lines to my .zshrc and reminded me to restart the shell. I moved the added export commands to .zprofile so that they were set after /sw/bin/init.sh is run. The commands were: export PERL_LOCAL_LIB_ROOT="$PERL_LOCAL_LIB_ROOT:/Users/dad/perl5"; export PERL_MB_OPT="--install_base /Users/dad/perl5"; export PERL_MM_OPT="INSTALL_BASE=/Users/dad/perl5"; export PERL5LIB="/Users/dad/perl5/lib/perl5:$PERL5LIB"; export MANPATH="/Users/dad/perl5/man:$MANPATH"; export PATH="/Users/dad/perl5/bin:$PATH"; NOTE! The MANPATH was NOT set by cpan config, tsk! tsk!, but I added it. So far all is well. I've used CPAN to upgrade or install several modules and they installed properly under ~/perl5, now let me see when I update the Fink modules that you all just updated ... stand by ... Looking good. It looks like Fink installs in the /sw tree and cpan installs in ~/perl5 and both coexist OK so far. cpan "sees" the Pod::Man in the /sw tree OK. But, I believe, it would install a newer version in ~/perl5. Extutils::MakeMaker is now version 6.64 in ~perl5 where I upgraded it prior to the Fink upgrade and 6.64 in all three Fink perl5 libs. It is 6.56 in the /sw/lib/perl5-core/5.12.3 library but I think that's OK. I suppose there could be a conflict where cpan installed a newer version that could break fink but I think that would be unlikely. As the install would be outside of the /sw tree it would be an easy remedy. So I think I have a good solution. And cpan doesn't run as root at all now which makes me think it can't step on anything Finkish or if it tries then I'll hear about it. The downside is that the installs are local to my userid but that's OK for me as I am the only likely user. And, of course, I can carry my ~/perl5 library along with me to the next OSX release. Otherwise Apple might very well step all over it if it was in /System/Library or /Library which is how it was with the "stock" cpan config. This has been fun. Color me happy for now.
