Interesting, never seen this error before.  Let's try forcing all the C
extensions to be recompiled.  First, make sure all yt installations have
been removed:

$ pip uninstall yt

Repeat that until it complains about not finding an active installation.

Then, in the root of the yt repository, run

$ bash clean.sh

clean.sh is a shell script that cleans up compiled artifacts.

Next, recompile

$ python setup.py develop

And let us know if that fixes the issue.
