Hi everyone, I have installed numpy 1.3.0 on Python 2.5.1 in an x86_64 machine, and it hangs when I do a numpy.test(verbose=10) on test_pinv (test_defmatrix.TestProperties) ... which I believe hangs on a call to numpy.linalg.svd. Can you please help me with this problem? The installation and configuration is probably a bit non-standard, so I am including the output of python -m numpy.distutils.system_info below. In particular, all the installation was done using CC='gcc -m32' to enforce 32 bit executables, as Python is a 32 bit executable here.
