Aaah... I see. nmake doesn't need cl.exe
per se, but it does so in connection with modules that contain code in C++. I suggest you try installing the
GNU development tools and utilities for Windows. They come with perl, a version of make and gcc, the GNU C++ compiler. They also give you the power of bash on Windows, so you should have seen a *nix-box at least from a distance.
Hope that helps, if not, drop me another note and I'll explain specifics.

Update
I think I might be able to get my hands on a machine that has both perl and Visual C++ installed. I might be able to rig up a binary for you, just drop me a line.
