It is also possible if someone uses fixed versions in buildout (like  
me) and starts to upgrade versions of individual packages step by step  
to see if the current versions work together with the project code (as  
I did).
It would be really helpful to know if an updated version requires new  
versions of other packages before seeing that the tests break. The  
version requirement produces is a much more explicit error message  
than an ImportError (which was the reason I added the minimum version).

I described above what I did. Fixing the version did not help me  
directly as this would require a new release of zope.app.component  
first, but it might help somebody else after a release was done.

Yours sincerely,
