The first two files enables building of plugins under macosx.

The third is for actually loading the plugins in blender.
For some reason its not identifying the plugins correctly,
but it compiles and runs so I'm including it hoping someone else
might see where I've messed things up...

I have a simple example at http://www.cs.umn.edu/~mein/test.tgz that
works, if anyone is interested in playing with it.
