The Cython installation needs to be inside the same Python
isntallation that yt is using.  Inside your new yt-i386 directory (not
sure why it's in /Applications ; usually it's supposed to go in your
home directory) can you run:

bin/pip install -U Cython

and report back the output?  Is this an old installation you are now
upgrading?  If so, I'd recommend wiping it out and starting a new if
you continue to run into issues.
