It should be relatively simple.
Download the oorexx_4.1.1.i386.deb package if it is a 32-bit system
and the oorexx_4.1.1.amd64.deb if it is a 64-bit system. Then run
from a command shell, as root,
# dpkg -i oorexx_4.1.1.XXX.deb
where XXX is the specific package, i386 or amd64.
I hadn't noticed that we didn't have packages with ubuntu or kubuntu
in the name on SourceForge. If for some reason the interpreter
doesn't work on your system, open up a support request and ask for a
package for Ubuntu 12 to be built, and I'll build them.
Those 2 generic .deb packages should work though. If they don't
you'll either see a crash on the first rexx program you run, or the
program simply won't run. It is not a subtle thing, if the first rexx
program you try works, then there is no problem.
Another tip if you have a 64-bit Ubuntu. Ubuntu didn't use to include
the 32-bit libraries needed to run 32-bit programs on the 64-bit
system. (But maybe they've changed that by now.)
You can fix that by adding the 32-bit library package. It's easy to
do, a google search should turn up the instructions. I just don't
remember the package name off the top of my head.
