NZBGet version 14.2 has been ported (2015/02/16) to OS/2.
"NZBGet is a binary newsgrabber, which downloads files from usenet based on information given in nzb-files. NZBGet can be used in standalone and in server/client modes. In standalone mode you pass a nzb-file as parameter in command-line, NZBGet downloads listed files and then exits."
