Hi,
I have spent some time trying to use different methods to build numpyon Windows 64bit with a version of BLAS/LAPACK other than the inbuilt one (no slur on the inbuilt one it is excellent, I am simply attempting to see if there is any alternative with better performance). The most recent i have tried is from here: http://icl.cs.utk.edu/lapack-for-windows/index.html
I used the installer and set the site.cfg file up in the following manner:
[blas]
library_dirs = C:\Program Files (x86)\University Of Tennessee\LAPACK 3.1.1\lib\x64
blas_libs = BLAS
include_dirs = C:\Program Files (x86)\University Of Tennessee\LAPACK 3.1.1\src
[lapack]
language = f77
lapack_libs = LAPACK
library_dirs = C:\Program Files (x86)\University Of Tennessee\LAPACK 3.1.1\lib\x64
include_dirs = C:\Program Files (x86)\University Of Tennessee\LAPACK 3.1.1\src
I have installed both intel's and pgi's fortran compilers in an attempt to get numpy to complete a compilation using these libraries, but have not been successful, both trip up at this point:

I appreciate any help or ideas anyone has,
