Hi Alexander, Excellent information. Thanks!
The comment about ActiveState PerlApp is very important. I don't want to make a program that only work with Active Perl. >From what you say, it seems like the best option might be: (1) Standard .deb or .rpm on Linux, (2) PAR on Mac, and (3) Cava on Windows, and hopefully "soon" Cava will be available in other platforms.
