Well, usually you will have installed either gcc or egcs a C compiler.
Unfortunately I do not know the rpm-version of gnat, but it looks
as though you try to compile an Ada program with a normal gcc (that
does not understand Ada).

You will need to make sure that the Ada-enabled gcc is in your PATH
before the standard gcc, which is in /usr/bin, I think.
If you do not know how to do that, you will need to get a book, or a
friend who knows Unix (or Linux :-) and learn some of the basics first.
Don't worry, after a while you will love it...
