Why doesn't it select python-2.7?
Pretty simple: The PYTHON_TARGETS variable is just another way to describe USE flags. And since you disabled all USE flags for subversion, you disabled both the USE flag, that enabled python-2.7 and the one, that enabled python-3.2. So the solution is also pretty simple: Dont do that.
Thanks for the explanation.
