You don't need a compiler to install a C compiler, you need a compiler
to *compile* a C compiler, just like you need a compiler to compile
any program.

If you just want to install gcc you use 'yum' or 'rpm' to do that,
instead of compiling it yourself.

If you want to compile gcc, obviously you need a compiler of some kind.

It might seem weird but it's not, it's quite normal.
