I see ... it sounds like your ISP installed openacs-core only.
The package installer's a bit rough in some regards, you're hitting a rough edge. We've not provided APMs for the various pieces at this point. It won't pick up packages that aren't local to the install unless they're in APM format, AFAIK.
What you can do is to copy the untarred packages you want under the packages directory of your actual OpenACS-4 installation. That's what the APM does when you feed it a .apm file, it untarballs it under the local packages directory.
Then when you to the install page they'll be seen by the APM, though I think you'll find you need to restart your AOLserver instance first.
If it was Marc (hub.org) who installed he was working with recent CVS sources, so make sure you pull packages from last night's tarball rather than the alpha tarball.
