+1.  This would also address the python 2.4 problem mentioned in
another thread.

BTW (if it is not already being done) it would be good for the
-recursive targets to check for BROKEN, FORBIDDEN, OBSOLESCENT,
(others?) in the dependencies _before_ starting the actual work,
since the presence of a problematic dependency may well affect
the user's decision to install/build/whatever the leaf port.
