This is what I've been doing for years. Then I replace /usr/bin/
perl with a symlink to /usr/local/bin/perl. This leaves me with a
default Perl install whose @INC does not include Apple's libraries,
only those in /usr/local/perl-5.8.x.
I never noticed any issues with this until recently I had occasion
to boot my PowerBook into single-user mode and at one point (I
believe it was when shutting down) I saw the following in an error
message ...
/System/CoreServices/RemoteManagement/ARDAget.app/Contents/
Resources/kickstart line 277
Can't locate Foundation.pm
Apparently a script related to Apple Remote Desktop Agent. And I
did find Foundation.pm at /System/Library/Perl/Extras/5.8.6/darwin-
thread-multi-2level/Foundation.pm (which of course is not in my @INC).
So my question is ... what is the best way to make sure my new
install (in /usr/local/) has everything the OS expects? Can I just
install a few extra CPAN modules and make the OS happy, or do other
apps install things in the Library/Perl dirs too?
What do the rest of you do?
For my part, I leave the symbolic link at /usr/bin/perl as it is. If
the system perl needs to be upgraded for some reason, Apple's system
update can do it. I keep my hands off the systems perl.
To use the parallel install of perl, I just put /usr/local/bin/perl
on the shebang, and/or edit the path in the .bash_profile script so
that /usr/local/bin comes first in the path.
