Konrad Hinsen's implementation in Scientific Python *is* in pure
Python, and as a consequence is probably about as simple as you're
going to get, I imagine.  Is it dependencies on Scientific Python that
you don't like?  If so, just dive in and remove them, if it's that
important to you -- I doubt you'll find a better pure Python
implementation.

I can certainly testify that SciPy's MINPACK wrapper works fine, too.
I can dig out some example code if you like.
