Non-root install fails.

Root install fails with "no cython" error.

Cython seems installed.

Forgive me if I'm doing anything stupid - I don't know much about running python on a mac. I believe I'm following all the instructions provided though, and I'm at a dead end.

I had the same issue and fixed after installing Cython.
