Sorry about that.  I have a tendency to over document...

I was afraid that would be the case.  I have gcc4sparc, but I usually
build with Sun Studio.  I believe gcc4sparc uses the Sun Studio
backend.  I'll try this, but do you know if I would need to do
anything different to get the ctypes code to compile?

Ok, so it looks like the only option here is to use LD_LIBRARY_PATH.

Thanks, Martin.
