[yt-users] YT installation

[Sherwood Richers]

Hi Matt,

I did that, but there now seems to be an additional problem. The tail
end of the output and install log are pasted below. I did as the
install log suggested and installed Cython, but the same error
appears, as if it doesn't recognize that it's installed (though
executing 'cython' puts up its usage page, so it's definitely there).
Again, thanks for your help.

Cython is a build-time requirement for the source tree of yt.
Please either install yt from a provided, release tarball,
or install Cython (version 0.16 or higher).
You may be able to accomplish this by typing:
     pip install -U Cython
