You must have updated one or more of your packages.

Looks like you have updated FFC (but not UFL) and not to the latest
version. The file uflcompiler.py is not there in the latest hg
version.

If you want a working installation, stay on the stable version for a
couple of more days. DOLFIN is currently broken as part of the
transition to UFL.
