Configuration problem

[Bob Edgar]

Hi. I'm fairly new at this sort of thing, so I'm probably missing something
obvious. I have downloaded and unpacked the 3.2.1 version of gcc. When I try
to configure it, it tells me that I have no acceptable c compiler in $PATH.
This is on two systems now, both Red Hat, one is v7.2, one v7.3. Isn't that
what I'm trying to install? Again, I'm new. If you can't help me, can you
steer me in a direction. I've tried Google searching, and have no joy.
Thanks!
