I saw those modules also, but after closer inspection, I believe they are modules to access the data in the palm database format - data that is synchronized onto your hard drive after a hot sync.

In other words, those modules are for applications that exist on your desktop computer, not your palm.

However, I found no modules for drawing PalmOS widgets, so I assumed it was not even remotely possible yet to write a Perl program to actually run on the palm....But I guess those existing modules will be used to access the data, should Perl on Palm ever become feasible.
