Hmm, the problem here is that this introduces unstated dependencies  
between these ports. Assuming the __init__.py file is required by  
both ports, consider what happens if you install py26-scikits- 
audiolab (will install __init__.py), then install py26-scikits-ann  
(will not install __init__.py because it sees it's already there),  
and then uninstall py26-scikits-audiolab (will remove __init__.py),  
presumably leaving py26-scikits-ann nonfunctional. And the same  
situation happens if you interchange the port names in the previous  
sentence.

I'm not sure how to handle this better, though.
