[yt-users] Error importing yt.mods

[Sam Geen]

So the setup.py script isn't copying the folder owls_subfind when it 
installs to the site_packages folder. If you copy this folder by hand 
the bug disappears and the import works fine. Bug 2) is probably just a 
side-effect of trying to import after it encounters bug 1), I assume.
