When building mod_wsgi from source code did you try:
./configure --with-python=python3
Ensure you first do a:
make distclean
to clear out old build from source directory if you have done a prior build in
the directory.
If you need an ability during development to be able to use either Python 2 or
Python 3, consider using mod_wsgi-express.
