[Numpy-discussion] Singular Matrix problem with Matplitlib in Numpy (Windows - AMD64)

Hello David.

I am using the Intel MKL BLAS/LAPACK. I have replaced this with AMD's ACML
library. Now there is no exception raised due to a "Singular matrix" while
trying to move the legend(wiggling the graph). So, the graph is updated and
the interaction is fine(you can wiggle the graph and it updates, minimize,
maximeie etc.). But ... the legend is now only drawn sometimes and the graphs
are drawn with an intermittent line, as if the - - -  pattern was specified.
Something is still not right. I just can't seem to put my finger on it since
there are some many parties involved(numpy,matplotlib,python, ctypes etc.)

I also ran the numpy.test() with NUmpy that I compiled with AMD's ACML. The
results are included:

OK (KNOWNFAIL=3, SKIP=1)

Thanks.
