Ahhh, I see, sorry, misread where the exception was coming from.

Surely the try:except for the NotImplementedError should be rwapped just 
around the call to imp.load_dynamic, then?

ie:

try:
   imp.load_dynamic(__name__,__file__)
except NotImplementedError:
   raise ImportError('load_dynamic not available so C extension cannot 
be used')

cheers,

Chris
