I can see the speed advantage in your suggestion: Modular X has
definitely resulted in massive bloat in dependencies with simple X
clients needing 60-70 dependencies.  This is _very_ noticable when
registering a package on a slow system.

I'm less convinced that it is possible to automate the process.

This won't detect dynamically loaded libraries.  mplayer appears to
dlopen() codecs.  Further investigation might reveal other examples.

My concern is that this is all manual effort and, so far, I haven't seen
anything that would let (eg) pointyhat automatically verify that the
dependency chain is correct.  Given the situation where A depends on B
depends on C but the Makefile for A does not list C as a direct dependency,
how does pointyhat verify this is correct?
