WITH_PYTHON needs to be enabled otherwise you loose almost all of blenders UI.
I'll add a waring on startup for builds with python disabled so this
doesn't happen again, this is only kept for testing/debugging

WITH_PYTHON_INSTALL is only for our own portable bundles to avoid
relying on the systems python which proved problematic in the past -
having to support multiple versions.

If the distribution has a python3.1 package that blender depends on
then this isn't needed.

Also noticed yafray is listed as a dependency in the spec file you
linked with, this can be removed.
