you have to create "binaries" directory in the Makefile

I have no idea how you created your source tree, but if you simply clone this repo the binaries directory is there:

OK, I see - if you unpack the source distro there is no binaries directory. We can add creating this to the Makefile but unfortunately Windows (and possibly OS/X?) do it differently so we need to be careful to do it in a way that's not gonna break things if the directory already exists. Linux is simple: 'mkdir -p' but I'm not a Windows or OS/X guy so can someone confirm a method that works for each of those, and also tweak the Makefile so it knows when it's running Windows?

I'm not windows guy neither, but here is what I found: http://stackoverflow.com/questions/3228306/portable-makefile-creation-of-directories

Windows mkdir always does what Unix mkdir does with the -p switch on. And you can deal with the backslash problem with $(subst).
