Replying to [comment:73 jpflori]:
> That's strange. Can you make sure the patch to the Sage library is
correctly applied (stupid question, but...) by looking at module_list.py

fine.

I do not know why during a test any compilation like this needs to be
done: recall that I had previously done sage -ba.
