Dear yt users,

I usually install yt on system python, following the procedure suggested me in this mailing list some months ago. In general everything goes fine with the installation and I can normally use yt.

Now I installed Ubuntu from scratch in my computer (where previously yt was installed and running!) and the installation seems to fine, but when I insert the command "from yt.mods import * ", I get the following error:

ImportError                               Traceback (most recent call last)

I would like to ask if someone has an idea of how can I solve this problem.
