That one's tough. Unless someone knows it off the top of their head (which does happen!), I, for one, need a bit more information from you. Tell us more about this error; like what module you're trying to install, and the exact text of the error message, and how you tried to install (using ppm install <Modules or URL> from command line, or by typing ppm and going into the app itself, etc.)

Your system's processing power will have very, very little to do with any kind of errors like that, if I grasp your error correctly. I've installed ActivePerl on my old P2 system w/no problems as of about 2 years ago, and I doubt it's changed _that_ much.

Listing the modules that are already installed is query * from within ppm.

Thank you, and let me know if any of this helps.
