On a related note, I get a similar error from within Sage. When I try to
create a free Z-module, Sage gives me an ImportError for core.numeric
(traceback included below). With this thread in mind, I tried reinstalling
ipython, but `make build` fails as well with a similar import error.
sage: M = FreeModule(ZZ,2)
