Yeah, I should have been a bit clearer here.  My point was that if this
facility were to exist, it would seem logical to support that kind of
mode of operation (since at least at one point vendors shipping binary
modules would seem to include a few enterprise distro builds and hope
that would cover it).  But that doesn't seem like a very good idea.

Auto-building schemes are better, but they still always seem to break.
