hacking setuptools to compile pyrex modules on OS X

I was trying to install rdflib 2.4 on an OS X 10.5 machine and got the error message

  File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/setuptools/command/build_ext.py", line 77, in swig_sources
    sources = _build_ext.swig_sources(self, sources) or sources
TypeError: swig_sources() takes exactly 3 arguments (2 given)


Most of the first google hits weren't so useful, so here's my fix. There's also the possibility of upgrading setuptools, but that might break the OS X specific things that apple did to it. (Or you could always install a parallel version of python, but that's just icky).

As far as I can tell, the third parameter is "extensions" used by swig_sources at python2.5/distutils/command/build_ext.py line 516.

It's only used occasionally and looks to be a way of adding additional command line arguments when running swig on line 561

I have no idea if *otherargs actually contains an object of the right type, but at least I was able to build the package with the pyrex extension in it.
