I tried to build a Debain package of the current Beta. It is available from http://dev.antiguru.de/oorexx-3.1.0.deb , please use it at your own risk as I never created a pakage before. It works on my own system, which is Debian testing.
Note to the admins: if the package doesn't cause any problems it could be placed in the file releases.
Please contact me in case there is something wrong. I tested a few scripts and they didn't show any problems.
