Dear Monika,
namdenergy is a proper vmd plugin. Is there any reason that you're trying
to use an old downloaded version rather than using the package that comes
with vmd?
package require namdenergy
should make the text interface available. See
http://www.ks.uiuc.edu/Research/vmd/plugins/namdenergy/ for how to use it.
Best,
Peter
