dev-lang/python, if the pkg supports py2k/py3k (specifically 
py2.{4,5,6,7}, py3.{0,1,2}), *is* the correct dependency.  End of 
story, no arguement is possible on that.

Note I said 'correct', not 'desired'.  It's the PM's choice how it 
chooses to fullfill that constraint.  Now, even if py3k is basically 
unusable (for anything reliant on a framework, at this point in time 
it is unusable), that *still* doesn't matter- the dependency is 

If you want to influence how the PM chooses what to use, that's 
masking or changing the algo it uses- not screwing up perfectly 
correct dependencies.

Considering that the algo varies across all 3 managers, masking is the 
only tool that exists atm.
