This is why versioning would be an useful solution.  Each package
would use the dependent packages that it requires.  Foo 1.0 uses
Bar 2.3 and Baz 3.2 uses Foo 1.4.  An application can use both Foo 1.0
and Baz 3.2 without having to mediate between their requirements.
While nobody is really requesting versioning, it seems to be the
solution to many problems that plague us.
