First, the viewers are always the most problematical aspect of Geant4 to make work. So disable them when starting.
Second,many people have installed Geant4 on various releases of Scientific Linux, which is derived from Red Hat Enterprise Linux. But you still have the problem of getting all the libraries correct. On Fermilab machines the upd/ups system assists greatly in getting a consistent set of libraries, and you might be able to install it on your machine to gain the benefit of their work -- then you wouldn't need to build Geant4 at all, just use their libraries. But I don't know if it works on Ubuntu, or whether there would be library incompatibilities.
Third, a potential short cut would be to download the G4beamline source from http://g4beamline.muonsinc.com . This includes complete source for all non-system libraries, and a build system that builds them all (plus G4beamline itself). On my 4-core Mac Pro it takes about a hour to build the libraries, and then about 2 minutes to build G4beamline, so that is not a large burden for just getting the libraries built. This includes the viewers, including Open Inventor (which is by far the most user-friendly of the viewers, but also the most difficult to get to work properly). You can cut the library build time in half by disabling Root when you configure G4beamline. (Wait a day or two, as a new release is imminent.)
