Comment (by michaelld@…):

 Unfortunately, SWIG 3.0.3 has some issues with the new Python wrappers
 that make it backward incompatible with 3.0.2. The SWIG devs are working
 on a fix, and will push 3.0.4 (or 3.0.3.1) out ASAP once everything is
 verified working. They consider this a critical bug, and I agree because
 the generated Python wrapper code is not valid (code generated by 3.0.2
 might not be easy to read, but at least it works). Once the fixes are in
 place, I'll update the SWIG ports. See also for more info:
 http://sourceforge.net/p/swig/mailman/message/33224489/

 All of the above said, I'm also trying to get a "swig-devel" set of ports
 in place for folks wanting to test the most recent commits.
