Binary modules compiled for one will not work with the other. That's why there's an architecture-specific subdirectory in the first place - it's not just there to annoy you! :-) If you want scripts that begin with "#!/usr/bin/perl" to use the Perl that's managed by DarwinPorts, you can delete /usr/bin/perl - it's just a link to /usr/bin/perl5.8.6, so you already have a backup. Then replace it with a symbolic link to /opt/local/bin/perl. Like this: sudo rm /usr/bin/perl sudo ln -s /opt/local/bin/perl /usr/bin/perl Note that if you do this, *every* script that begins with "#!/usr/bin/ perl" will be using the DarwinPorts Perl - including the scripts that Apple supplies, which have not been tested and verified with that configuration. As you've said, the difference is small, so problems are very unlikely, but still possible. The safest route is to leave /usr/bin/perl alone, since Apple- supplied scripts don't rely on any external modules anyway, and use "#!/opt/local/bin/perl" in your own scripts, so that they use the DarwinPorts Perl and any modules you've installed for that. sherm-- Cocoa programming in Perl: http://camelbones.sourceforge.net Hire me!

Finding the current user
I know I can get this with `whoami`, but I was wondering if there was a "Perl" way to find the user who executed the script.

The reason for 2 versions is a port system that >refuses to rely on the already installed perl. Try setting the PERL5LIB environment variable. It's formatted like a $PATH for perl. I set it in $HOME/.MacOSX/environment.plist so that it works when initiated from a Cocoa or Carbon application. You may have a problem with incompatibility of stuff in an @INC area that demands another version of perl.

@INC
How can I permanently add to @INC? I have 2 versions of perl
installed and only use one of them. The reason for 2 versions is a
port system that refuses to rely on the already installed perl. So I
have:
$ /usr/bin/perl -e 'print join("\n", @INC)'
/System/Library/Perl/5.8.6/darwin-thread-multi-2level
/System/Library/Perl/5.8.6
/Library/Perl/5.8.6/darwin-thread-multi-2level
/Library/Perl/5.8.6
/Library/Perl
/Network/Library/Perl/5.8.6/darwin-thread-multi-2level
/Network/Library/Perl/5.8.6
/Network/Library/Perl
/System/Library/Perl/Extras/5.8.6/darwin-thread-multi-2level
/System/Library/Perl/Extras/5.8.6
/Library/Perl/5.8.1
AND
$ /opt/local/bin/perl -e 'print join("\n", @INC)'
/opt/local/lib/perl5/5.8.7/darwin-2level
/opt/local/lib/perl5/5.8.7
/opt/local/lib/perl5/site_perl/5.8.7/darwin-2level
/opt/local/lib/perl5/site_perl/5.8.7
/opt/local/lib/perl5/site_perl
/opt/local/lib/perl5/vendor_perl/5.8.7/darwin-2level
/opt/local/lib/perl5/vendor_perl/5.8.7
/opt/local/lib/perl5/vendor_perl
I really only want to use /usr/bin/perl, but the port system will put
modules into the /opt/local/bin/perl version which I want to use
from /usr/bin/perl.
Thanks!
