Parrot/2 came about after a challenge to one of the Parrot developers, Alex Gough, who's a good friend of mine. It was thought that getting the parrot bytecode interpreter building on OS/2 with EMX would be a challenge for him. Alas it wasn;t, and we'd got a happy tinderbox system building cleanly from cvs inside 3 days...
So, to build Parrot for OS/2, you'll need the EMX development tools, and
a few other things. See
for details on what you need, and how to set it up. It should be really straight forward after that.
