I would like to recommend the "mock" [1] tool for building SRPMs in RH
environments. It basically builds a minimal chroot and then builds the
SRPM in the chroot using only the RPMs specified by the SRPM.

It's nice if you're creating your own spec files because you can make
sure that you're correctly specifying all of the dependencies and you
don't end up polluting your build machine with hundreds of -devel
packages. It also allows you to build RPMs for different major
RHEL/fedora releases without requiring an install of each environment.
