You need a modern perl (e.g. perl5.004 but older versions may work
too). If you want to use the Tk interface (and that's the only
reason why bother with this module), you need also Tk402.202. The
module Data-Dumper is optional. All of these may be found at a CPAN
site, e.g. ftp://ftp.cs.tu-berlin.de/pub/lang/perl/CPAN/.
