How to build a RPM with circular dependencies?

I am trying to build mesa-7.6-0.1.fc11.src from source.

$ yumdownloader --source mesa
$ cd rpmbuild/SPECS
$ rpmbuild -ba mesa.spec
error: Failed build dependencies:
        freeglut-devel is needed by mesa-7.6-0.1.fc11.src

No problem. I will download this dependency from source and build that first.

$ yumdownloader --source freeglut-devel
$ rpm -ivh freeglut-2.4.0-16.fc11.src.rpm
$ cd rpmbuild/SPECS
$ rpmbuild -ba freeglut.spec
error: Failed build dependencies:
    libGLU-devel is needed by freeglut-2.4.0-16.fc11.src

It looks like I need another package. Let’s see which source RPM is needed to build it.

$ yumdownloader --source mesa-libGLU-devel
Loaded plugins: refresh-packagekit
mesa-7.6-0.1.fc11.src.rpm                       | 7.1 MB     00:00

Alright… so mesa needs freeglut-devel which needs libGLU-devel which is built by mesa. This is a circular dependency.

When considering only building from source and not installing a prebuild package, how can this circular build dependency be resolved? libGLU-devel is only one of several RPMs that is built by mesa. Is it possible to build only that one RPM instead of all of them to see if this avoids the dependency on freeglut?

What is the correct way to resolve this circular build dependency?

For context, I am building packages from Fedora 11 from source for testing DRI drivers that only exist on very old kernels.
