However, I'll still try to figure out what was up with the MinGW install. Just as an aside, the Numpy installer for Python 2.6 has always run really slow when compiling and optimizing. Consequently, the first time I import and use Numpy with Python 2.6, it is extremely slow. This is independent of building using MinGW or MSVC, 1.4.x branch or trunk. I don't have this slow down with the Python 2.5 installer, nor when I import and use Numpy with Python 2.5. Thanks for the help!
