And you still get the error that 'nmake' is not recognized as an internal or external command,operable program or batch file ? (Are you sure about that ?) I don't know how that could possibly happen.

He wrote that he has "already install the Nmake.exe in my perl directory". Now I don't know into which "perl directory" he has installed it, but I suspect that it may not be one actually in %PATH%, but possibly the one in which he is developing code, and nothwistanding the fact that . is usually in %PATH% in Windows systems, it won't be the build directory for Inline builds, IIRC.
