[PLUG] rpm source package building

[Larry Brigman]

My goggle foo is not doing too well in finding an answer to this
question (if there is an easy one).

My problem:

I need to build source rpm packages from tarballs that are not in any
distribution (newer versions,
custom patches).  I do plan to build  the binary rpm in a chroot to
isolate the build dependencies via
a build package called mock.  The problem is that mock needs a
prebuild source rpm.

The other half of the problem is that when building the source rpm,
rpmbuild does a check of
the Buildrequires packages before it build the package.  These are
only needed when building
the binary package not the source package.

Is there a method to construct the source rpm without it requiring all
of the Buildrequires packages being
installed on the system that is building the source package?
