Ahh ok, well that makes more sense, but yes, I did do a 'make clean' as part 
of trying to solve the problem.  I have just done it again to make absolutely 
sure, and I'm still getting the same error.

I've uploaded my .config here if it will help:

Let me know if you can figure out what I have done wrong!

Thanks again,
Adam.
