Thanks Marcus.

I did a "sudo ldconfig" but to no avail.

I am wondering if the problem is destructive interference between the apt-get 
install of the binaries
and my attempt to install using PyBOMBS?   If so, is there anything I should do 
to get rid of the PyBOMBS
other than an "rm" of the installation directories?

That is almost certainly the case.

What installation prefix did you have PyBombs use? I think it will have instructed you to use an env.sh, or setupenv.sh, which will contain settings of LD_LIBRARY_PATH, PYTHONPATH, etc. If you simply log out, and log back in, and don't run that setup script,
  you may be OK, without having to uninstall the PyBombs-installed stuff.

But I'll point out that GR+friends installed from packages are going to be out-of-date, sometimes, spectacularly.
