[IPython-dev] isympy doesn't work with the new ipython-dev

Erik,

This approach will also work.  With the current trunk, you shouldn't even
have
to move the ipython_config_sympy.py to .ipython.  But if you do move it
over,
you can change it to your taste.  Can you mention this on the sympy list to
see what approach they want to take?

Cheers,

Brian
