To demonstrate my idea, I've updated the SRPM builds in octave-forge
with the ideas discussed. If you take the pkg.m from the CVS with a
2.9.10 RPM installed then the attached SRPM will build to an RPM that
can be installed with the "rpm -Uvh", can't be uninstalled with "pkg
uninstall <package>" and contains architecture dependent directories.

I also attach the corresponding SPEC file for the SRPM if you aren't on
an RPM based system so you can see how I modified the SPEC.
