[broken ports]

There are several more (e.g. graphics/blender), which suffer from the  
same issue.
For those, who wonder what is going wrong here:

The interim hack in bsd.python.mk, which always causes ports to pull in
lang/python, if USE_PYTHON[_XXX] is set, is the problem. As some know, I am
currently testing all ports for that problem and am making lang/python  
a dependency
on the port, rather than being implicitly set by bsd.python.mk.
Once done, the ports themselves will need to be fixed to use the  
proper python version
rather than lang/python, so we can build version-specific packages.

Long story short: No port should depend on lang/python at build and  
installation time
as a mid-term goal.

For those with too much free time at their hands: feel free to go  
through John's list
and fix the ports to use a proper python version at build time instead  
of `python` :-).
