[Numpy-discussion] Superpack - one Complex test failure

Finally I got my Wine environment sorted out - I'm now able to build
superpack installers for both Python 2.5 and 2.6. I tested the 2.6 installer
on Windows XP, and got a single test failure. This exact same test also is
the only test failure with the numpy 1.3 installer on sourceforge. So the
installer seems fine to me, and either it's the machine on which I'm testing
or this test just fails on windows. What do other people see when using an
installer from Sourceforge?

For completeness: the installed version is SSE3, processor is Intel Core Duo
