I'm getting an error message running a TCL script that's calling the program VMD. Trying to track down the source of the problem is frustrating me to no end. I know that these same scripts are working fine on a university-owned research server (which I heard the VMD developers kindly installed VMD on themselves), but when we try to use them on our own server we run into this problem. Here's the relevant portion of the output. If anyone knows where to direct me for some help with this it would be greatly appreciated and save me years of therapy down the road.

  Thanks,
