I think I've figured out a way to make this almost work::
  import sqlalchemy

is equal to Requires python(sqlalchemy)

Any of these::
    install_requires = [ 'SQLAlchemy' ]

are equal to python-egg(sqlalchemy)

This breaks down when thinking about what happens in this case::
  import pkg_requires
  import sqlachemy

At this point you have to know whether TurboGears or anything that it
requires has a requires.txt which includes ['SQLAlchemy'].  If it does
we are using the egg interface to sqlalchemy.  If it doesn't we are
using the normal interface.

So, assuming we remove our patch that stops generation of egg-info files
for distutils generated modules for F9, I agree that there isn't very
much value for quite a bit of work.
