Note that while the binaries may be slow to arrive on sourceforge.net at the moment, they can also be found in the Releases section of the github site, https://github.com/OpenMathLib/OpenBLAS/releases. Binaries for other platforms are usually available on the sites listed in the OpenBLAS Wiki

Install from Source
