OK, this is one thing I need to try.  I have running with Python 2.5
right now.  I will try 2.6.  But, there are other odd things...

Hmmm, I did not have to do this step.  What errors did you see?  This
is odd.  With that said, my Python
is compiled with Mingw, which may be part of the problem.

Even more odd.  After I compile the Python extension, I don't even get _zmq.so,
Instead I get _zmq.pyd, which I guess is a .dll with a few differences:


Not sure why you get a .so though.

Final odd point:  I checked _zmq.pyd and libzmq.dll and depends.exe
complained that it couldn't find
3 DLLs:


I am going to try with Python 2.6 and do some further investigating
these things.  Seem like these things
could definitely be related.
