What's happening is that it's trying the old script, which is failing
for some reason, and then trying the new one.  I had thought that maybe
the old one wasn't present, but apparently not.

The X11 error suggests a possible thing to try.  Edit
/sw/var/lib/dpkg/info/openmpi-ext-oct362.prerm as a superuser and change

/sw/share/octave/3.6.2/openmpi_ext-1.1.0/octave-forge-prerm

to

xvfb-run /sw/share/octave/3.6.2/openmpi_ext-1.1.0/octave-forge-prerm

and then try updating openmpi-ext-oct362 again.
