Oh hang on, it's that Asus customised Xandros install that they put on the EeePC isn't it. The one about which people tend to complain when they assume it's the sort of install you get if you had installed Xandros/openSuSE/Fedora or whatever from a DVD buy then find they can't do what they want to do because the Linux build that the EeePC ships with is designed on the assumption that you use what's on there, not that you will want to start compiling your own software on it. You might well not even have a build-essentials package available to install.
I forget to say before that in my experience not only is cc in the same directory as gcc but it's in the same package. So if gcc is installed so is cc. Also they're both in /usr/bin which is in $PATH by default. That may not be the case with Xandros though. Do you actually have gcc installed? What does
say? If it doesn't say anything then you probably don't have gcc installed.
If I were you I'd put 'eeepc forum' in to Google and look for info on how to do what you're trying to do. That or replace the Linux install entirely with Aurora/Eeebuntu.
