Linux.  I do not believe there is a FreeBSD one.

Thanks for that I will look into that port.

I have had some success since I first sent the email.
I have compiled linking to the static linux libm and libc libraries.
(Could not work out how to do that in setup.py so just ran on command line).
Importing mathlink now gets further and truss shows

stat("/tmp/MathLink",0xbfbfd670)                 = 0 (0x0)

This could be related to fact that Mathematica does not support
Python 2.4 and MathLink so I'll try installing python 2.3.

thanks
