SCons includes two rpm things - the packager and the tool. The packager,
called through the Package builder, which attempts to construct a
specfile first, indeed seems a little flimsy, but the tool, which sets
up the Rpm builder, doesn't seem to do much more than your suggestion -
call rpmbuild given a .tar.gz.   For reasons not clear to me, there is
no documentation entry for the Rpm builder - nor are there any direct
tests of it. Odd (note: we should do something about that).

Anyway - have you looked at the Rpm builder?  Would it work in your
decoupled scenario?
