actually, I'm not in agreement here. If I install libfoo, be it from
binaries or source, I certainly expect to be able to use libfoo, and
that includes being able to build software against it,  things I work on
myself, other sources, or sources from Gentoo.

We can hack around the later by being fanatical with our own DEPEND
tracking, for the other two, our tree will remain completely broken.

This is a case where we, a source based distro, is actually a crappier
development platform than any of the current binary distributions.
