Ha! I finally gave up on the VMD plugin years ago and used gnuplot. Not the most amazing molecule visualization program, but at least it worked.
I can't be much help, but will second and applaud anyone who takes a stab at making it work.

Re-directing to Amber-developers: it would be great if difficulties with IED
could be resolved, most likely by someone who wants the solution. There are
some improvements beyond installation needed, mainly in having a nice
interface to control the visual amplification of the modes. I'll see if an
undergrad with python experience can look at this, but anyone else is free to
jump in.
