The way I handle this with non-perl packages, is I insert a "fake"
provides in the spec file for the thing that rpm will detect as a
dependency.  cpanflute2 presently supports the --requires option,
and it would be real easy to create a patch to support --provides.
Well I just did, so if you download the RPM-Specfile from cpan (the 1.13
version) and apply the patch found at:

	http://lee.k12.nc.us/~joden/misc/patches/provides.patch

All you have to do is something like:

	cpanflute2 --buildall --provides="perl(lib1) = ver1" ...
		--provides="perl(lib2) = ver2" tarball

And your problem will go away, while yet still allowing the "real"
dependencies to be tracked.

Cheers...james

P.S.  Chip don't download the patch if you see this, as I need to
clean it up.  I think its time for pod for cpanflute2 itself (-;
