[ITK] [ITK-dev] cannot enable python wrapping in ITK

Normally if you are building with latest git master, you should not be able to build with SWIG 2.0.11
There is a check which asks for 3.0.0. That's why we ship our own swig built as an external project.

I recommend you set ITK_USE_SYSTEM_SWIG=OFF.
Maybe try working from a clean new build directory.

I will see if I can test this soon on Fedora 20 but I bet this is not OS related.
