My impression is that the IBM software is binary only. If that's true, I am not
likely to be able to run it on OpenBSD. OpenBSD has a Linux emulation mode,
but I don't use it because of my concerns about security.  I think the sw
development tools used are modified GNU tools(GCC, etc). I would expect those
to be available as source.
