The --print-multiarch thing looks very questionable. As far as I can tell, it's a Debian specific gcc patch, only available in gcc 4.6 and up. Ubuntu before 11.10 release also doesn't have it. Therefore I don't think use of --print-multiarch is appropriate for numpy for now, and certainly not a change I'd like to make to distutils right before a release. If anyone with access to a Debian/Ubuntu system could come up with a patch which adds the right paths to system_info.py, that would be great. Ralf
