Importing sdl2 in python3.3 gives PYSDL2_DLL_PATH: unset

[Russell-Jones-OxPhys (Russell Jones)]

I guess I could set this manually, but shouldn't it be set by macports, e.g. in the module?

$ ipython3-3.3

Hmm, yeah. import ctypes.util; ctypes.util.find_library('SDL2') returns None in python3.3 (as opposed to '/opt/local/lib/libSDL2.dylib’ in 2.7). Not sure if ctypes needs fixing (to search in ${prefix}/lib for example) or if I should just hardcode the path to the lib in the python code.

Fixed in r118683. It complains that a bunch of functions are missing at import time, but the examples seem to work fine.

I think there’s still probably a good case for having our ctypes look in ${prefix}/lib all the time.
