The Netomata tools are written in Ruby. We've developed the code under Ruby version 1.8.6; we haven't yet tested it under other versions, such as the new Ruby 1.9. You can find out what version of Ruby you have with the "ruby -v" command.
The tools should run just fine on any UNIX or Linux system (including MacOS X; that's where we do most of our development, as it happens). We haven't tried them under Windows yet, but they'll probably work there too (if not, let us know what problems you ran into by email to bugs@netomata.com, and we'll see about fixing them so that they do).
In addition to the standard Ruby libraries, the tools also requires the Facets and ruby-debug gems. You should be able to easily install these gems, if you don't already have them, with the commands "gem install facets" and "gem install ruby-debug".
