OK. I tried this:
- clear out old numpy from ~/local
- unpack fresh numpy 1.6.1 in a build directory and cd into it
$ python setup.py config_fc --fcompiler=gnu95 build
$ python setup.py install --home=~/local
$ cd
$ python
$ import numpy
$ numpy.__file__ # to make sure it picked up the newly build version
$ numpy.test()

Again the unit test fails with:
FAIL: test_lapack (test_build.TestF77Mismatch)
----------------------------------------------------------------------
Traceback (most recent call last):
  File 
"/astro/users/rowen/local/lib/python/numpy/testing/decorators.py", line

line 50, in test_lapack
    information.""")
AssertionError: Both g77 and gfortran runtimes linked in lapack_lite ! 
This is likely to
cause random crashes and wrong results. See numpy INSTALL.txt for more
information.

P.S. I'm using nose 0.11.4 because the current version requires distrib. 
Surely that won't affect this?
