Comment 6 for bug 344440

Does anyone know why can't we get the updated version of openmotif in the repos? Is there a reason or just nobody got to do it yet cuz it's low priority.

As for workarounds yes there are two:
One is simply to create a link called libXm.so.4 which points to whatever version you get when you install from ubuntu repository. I have not tried this one but reports on all sorts of forums say it works

The other one is to use alien and convert an rpm version of the latest openmotif (I used 2.3.1) and then rip-out the linXm.so.4.xx library and copy it into /usr/lib. Then create a link called libXm.so.4 pointing to that library.

The second method gives you the newest version of the library but needs a bit more work.
