nmake 'nmake' is not recognized as an internal or external command, operable program or batch file.
Appears you don't have a build environment installed, and that amatch doesn't give you any binaries, meaning...you need a build environment As alpha Blue noted, the easiest way is to download/install mingw + devkit [devkit is mingw compiler] and hope it builds at that point, or switch to linux or cygwin [or drop that extension].
