Most (maybe all) of the libwin32 modules are available as PPM modules at http://ppm.activestate.com/PPMPackages/, which is easier than building them.

In fact, I think a lot of them are bundled with Activestate Perl, depending on which version you have.

If you do need to build them, you must use nmake, not the gnu make, which gives the "missing separator" error.

You didn't say:

1. what version of windows you have
2. what version of perl you have
3. what version of nmake/MSC you have
4. what happened when you ran nmake (other than "it bombed")
