this is related to your language settings.

please check whether the first line of your vmd startup
script is '#!/bin/csh' or '#!/bin/sh'
in the first case add the line

setenv LC_ALL C

in the second case the lines

export LC_ALL

right after it and try again.

not sure if this is related. please be more specific about "cannot load".
you should get an error message in VMD terminal windows, what
does it say? or what else is happening or not?
