[SciPy-user] FAIL tests, seems fftpack related, check_dot takes forever.

Problem:
check_dot (scipy.lib.tests.test_blas.test_fblas1_simple) seems to take
forever on my system, been running at 100% CPU time for at least five
minutes on this P4 3GHz machine, I cancel the test at the end.

Several FAIL tests related to fftpack, not sure they are important or not.

Can some one point me a direction to resolve the problems or indeed is
there a problem to begin with?
