Hi Conrad,

Looks like pip is not managing to find your compiler, though if you have
installed XCode that should be in place.

What do you get when you type "gcc" at the command line?

Assuming that indicates that the shell can find your compiler -- you should
get a message indicating that the compiler couldn't find any input files,
or something to that nature -- does typing (as suggested here:

export CC=gcc

and then running:

pip install dipy

do the trick for you?
