Hmm. I'll just be saying what's in the CB right now

Looks like silicon39 is tired of waiting for the actual admin to install Perl. And gcc isn't on there either. Yech!

I have gone through the trouble of installing Perl on an HP. 10.20 even. It was hell for me at the time, because I kept finding incompatiblities between different versions of HP-UX. That and a compiler was not included, but this was in 1998, maybe it's better now. If this machine isn't used by other people and you can afford to totally screw it over, play with it and try the various installs. You'll learn a lot in the process.
