Apple suggested I install something the other day. (Java or something like that.) I did it. Now I discover that many of my Perl scripts don't work.

The problem is with @INC. It appears to have been upgraded to Perl 5.8.8. For example, when I try
use Date::Parse qw(str2time);
I get the message
/Volumes/VTN Docs/ My Perl/Tests/test5.pl:6: Can't locate Date/Parse.pm in @INC
followed by a list of what @INC contains:
/Volumes/VTN Docs/ My Perl/Tests
/usr/local/lib/perl5/5.8.8/darwin-2level
/usr/local/lib/perl5/5.8.8
/usr/local/lib/perl5/site_perl/5.8.8/darwin-2level
/usr/local/lib/perl5/site_perl/5.8.8
/usr/local/lib/

The package "Date/Parse.pm" is right where it has always been, along with a whole pile of other stuff, in
/Library/Perl/5.8.6

So this is my question. How do I add "/Library/Perl/5.8.6" to @INC, without having to add
use lib "/Library/Perl/5.8.6";
to every script ?

Regards,

Vic

That's not Apple's Perl, or anything that resulted from the recent
Apple update. I've looked through the recent Apple update receipts,
and didn't find anything Perl-related. You can use lsbom to check the
contents of anything installed from .pkg or .mpkg packages, which
includes Apple updates. The receipts are in /Library/Receipts, so to
find the.boms for packages installed in the last 7 days:

find /Library/Receipts -newerct '7 days ago' -name '*.bom'

Then, to browse the list of files installed by a package using the
"less" command:

lsbom /Library/Receipts/JavaForMacOSX10.4Release5.pkg/Contents/
Archive.bom | less

Possibly, someone replaced all your scripts #!/usr/bin/perl with #!/
usr/local/bin/perl. Maybe you did that to test them against the newer
Perl and forgot to change it back, or maybe someone in your house has
a strange sense of humor. :-)

If your scripts still say #!/usr/bin/perl, then something has removed
the original /usr/bin/perl and replaced it with a link to /usr/local/
bin/perl. You can check that with "/usr/bin/perl -v".

Fortunately, the original is also a link, to /usr/bin/perl5.8.6, so
if it was disturbed, it's easy to make things right:

sudo rm /usr/bin/perl
sudo ln /usr/bin/perl5.8.6 /usr/bin/perl

I don't have that strange a sense of humor, Sherm, and I'm the only one in the house who works with Perl. The bang lines on my problematic test routines all read "#!/usr/local/bin/perl" and the bang lines on good routines read "#!/usr/bin/perl". I think my computer may be infected with gremlins.

I've changed everything to read "#!/usr/bin/perl" and now everything works. Thanks so much for your help! Unfortunately most of this system stuff is a mystery to me.

Regards,

Vic

It's likely that there is abetter way, but. . .

If you define the environment variable PERL5LIB in your $HOME/.MacOSX/environment.plist file you can add directories to @INC which will be present no matter what shell or scripting language you are using. There is an Apple-provided app note about environment.plist.

What I worry about is the older functions in 5.8.6 may not work.
