Thanks Robert, mystery solved; the source was there but I had changed
the Makefile to not build for complex variables after reading about
RH's problem, and then forgot to put it back. At last, I can now import
numpy! I don't have any use for complex variables, so I hope the broken
tests don't imply anything for the reliability of the library on my
system.
Thanks again,
George
