Comment (by gbburkhardt):

 For build and install, I am using:

 python setup.py build --fcompiler=gnu95
 python setup.py install

 I changed the permissions, and the test ran:

 numpy $ pwd
 /opt/gnu/python-2.5.2/lib/python2.5/site-packages/numpy
 numpy $ find . -name "test*.py" -exec chmod -x {} \;


 But there's a new seg fault:

 ... lines omitted...
 Tests median w/ 3D ... ok
 Tests notmasked_contiguous ... ok
 Tests unmasked_edges ... ok
 Tests polyfit ... ok
 test_atleast1d (test_extras.TestShapeBase) ... ok
 Test creation by view ... ok
 Test that 'exotic' formats are processed properly ... ok
 Test filling the array ... ok
 Tests fields retrieval ... Segmentation Fault (core dumped)

 I recompiled without optimization, and ran under 'gdb'.  The log 'numpy-
 segfault-3.3.09' is attached.
