I know this discussion first took place months ago, but I'd like to know 
whether or not you find a solution to the SxS assemblies issues using 

In case you haven't (the binaries package for windows is built using 
mingw), I'd like to know if this would be possible to relocate all numpy 
*.pyd from their original location (i.e. site-packages/numpy/core/, 
etc.) to the main executable one (i.e. python.exe).
AFAIK, this would eventually solve the redistributing issue we are 
facing with python extensions built with SxS policy. Indeed, both 
Microsoft.VC90.CRT.manifest and msvcr90.dll files are located next to 
the python.exe executable in the standard distribution 
(http://www.python.org/ftp/python/2.6.4/python-2.6.4.msi). This way, all 
numpy *.pyd extension would be able to use these files (considering that 
python and numpy are built using the same revision of the crt library). 
IIRC, the SxS look-up sequence starts with the dirname of the 
executable... (i.e. ./python.exe/.)
