Somehow, installing Clisp on these three systems took somewhat different amounts of time.
Mac OS: Five weeks. Installing macports was the worse part. Still can't get emacs and slime together.
Linux: two weeks, gave up when I got Clisp to run in the command line interface.
Windows: Five minutes.
I have no idea why this is, but for a noob, it takes five minutes to get Clisp on slime up and running on windows XP.
I am aware that it takes someone experienced very little time. But this is what it takes a noob who has to find out firsthand how to deal with glitches in macports and such.
I'm also aware there's probably a download site that is much more user-friendly than the others. But this does not take away the fact there are many user-unfriendly download sites, and it's hard to tell them apart if you're a noob. So, just putting this out there; for some odd reason, you can install clisp on windows xp if you go to

and you'll be done in five minutes.
Sorry for the rant. It's just frustrating: I had high expectations for it.
