Download and read the README.OS2. There are now a lot of dependencies,
the simplest is to use the Arca Noae Package Manager (ANPM). See Steve's
Warpzilla page at
http://os2news.warpstock.org/Warpzilla.html for the
URLs and zips of the dependencies or if you want to go the RPM route,
simplest is to install
https://repos.arcanoae.com/anpm/anpm_1_0_0.exe
The YUM/RPM route is kind of crappy and not really in the spirit of OS/2
but it does make things simpler and more and more programs have
dependencies that are best managed with it.
