in reply to What could I do with just Perl?

By all means reinstall Perl as Zaxo suggests. Then download yum from Duke University and ask it what modules you need. I am the most ignorant Perl programmer in the world and I can get it to work. If you are not familiar with it yum = Yellowdog Updating Module. I think it works for the Mac.
Good luck,

Perl has one Great Advantage and one Great Disadvantage:

It is easy to write a complex and powerful program in three lines of code.
