Sure, but if you can build packages on the fly, transparently to the
user... it is a "six of one, half dozen of the other" situation.  I
would expect there to be situation where autobuilding would fail or
not be practical (C based modules), supporting "binary" packages would
be a necessity.

Ya, RPMs are not known for doing a good job of dependencies.  Debian
would be a better model to look at with respect to what dependency
info is required and how it should be handled.  I rarely (can't
remember the last time) have dependency problems with DEBs, that
includes third party DEBs (they usually have problems with "Policy",
but that's a whole other story ;).
