demandimport error - ImportError: No module named fs

Created originally on Bitbucket by Kim_Rydhof_Thor_Hansen (Kim Rydhof Thor Hansen)

This might be the same problem as #29 (closed), but the error is a little different.

I have it using Debian unstable with mecurial_keyring directly from the repository.
