now this is looking serious. however, it does not directly
mean, that libstdc++.so.5 is the offender, but a library
that it depends on.

please try:
ldd /usr/local/lib/vmd/vmd_LINUX

and report the output. it should be something similar to:
[akohlmey_at_zero akohlmey]$ ldd /home/akohlmey/lib/vmd-185/vmd_LINUX

always very obvious in its error message.
