I think it's probably not really broken. (I use it sparse.linalg.spsolve 
quite often, and see the umfpack deprecation warnings...)

Can you check your build log if the umfpack extension was really built? 
(It's supposed to fail "silently" if it can't be built so that the rest 
of scipy.sparse still functions.)
