Hi Phil,

Sorry to bump a thread, but anyone got any more ideas re. cause or 
anything else I can attempt? Why would it be that python (imp) doesn't 
know how to load C extensions as the traceback implies? Are there any 
defines that need changing in pyconfig for example to allow this?

Thanks, Rob
