If you do have Microsoft's Visual C/C++ installed, then you need to first run the batch file "vcvars32.bat" in the same console window in which you're going to try building the package.

Microsoft does offer a zero-cost command line compiler these days, but I don't know the details of how one builds packages for activestate with that compiler.

Another alternative, and probably your best bet, is to find a place where someone else has already compiled Crypt-DES for you and is offering the files out for others. To find such places, google for "Crypt-DES.ppd" and take note of the results. Once you find such a place, you can add it to your ppm3 with a command similar to:

rep add webpub http://perlpack.webpub.net/

Note that this last option is equivalent to running some binary that you just found "out there" on the internet, with all the security craziness that implies.
