since you're using rh9.0, it should have come with gcc 3.x
, followed by a .
to show you where gcc is.
since it says that it cant find a compiler, check your PATH from your terminal with:
do you see your path to GCC in what $PATH is? if not ... edit your shell rc file (or if you want your profile under /etc) to include the path to gcc at startup.
hope that helps.
