what happens when you follow the pip install instructions?

for conda, there is already an issue open: #120

I get an error about the gcc compilers. I think it's a clang issue, and I tried switching to a conda install to see if that helped, but I got the same error (copied at end).

If I do a direct install from the cloned repo I get a cython error, which is very puzzling since cython is definitely installed an up to date, but that might be a python version mismatch issue.

None of this happens when I install on linux - everything works fine there - and it's not super important, I just wondered if something had already been worked out. No need to spend time on it if not.
