Hi, the numpy win32 binaries on sourceforge do not contain any proprietary code. They are build with mingw 3.4.5 and are using a f2c'd version of netlib blas and lapack which so far I know is public domain. I think the macos wheels on pypi are built using ATLAS but they do also contain libquadmath which is LGPL licensed. Its probably pulled in by fortran (could maybe be removed by a rebuild as neither blas nor numpy use it) There are also unofficial win64 binaries floating around, I don't know what they are using, but its possible they contain MKL, you need to check with who is building these (Christoph Gohlke I think). Cheers, Julian
