fails with python 2.5 fails with python 2.5

python -o linux -v -p user-sph -cc mpi -fft none -jpg no -a file mpi
Traceback (most recent call last):

    i = makeclasses.index(switch)
AttributeError: 'tuple' object has no attribute 'index'

I think the reason is that in python 2.5 tuple does not have index().
See the changelog

ok - I guess you need to use a more modern Python, e.g. 2.7.
