[Numpy-discussion] Built Lapack, Atlas from source.... now numpy.linalg.eig() hangs at 100% CPU

[Chris Colbert]

just to see if it would work. I compiled against the .so's and just didnt
worry about the linking error. Then i installed numpy and ran numpy.test()

these are the results:

Ran 2030 tests in 9.778s

OK (KNOWNFAIL=1, SKIP=11)
<nose.result.TextTestResult run=2030 errors=0 failures=0>



so i guess that means its ok..
