I am almost desperate and any prompt help is greatly appreciated!

We tried to connect Novint Falcon (http://en.wikipedia.org/wiki/Novint)
through VRPN with IMD and let Falcon control the molecules by following the
instruction on this page:
http://sites.google.com/site/akohlmey/software/vrpn-icms. Here are some
specs of the machine and the software.

1. Linux machine (AMD64, Red Hat 5.4)
2. Latest VMD (Version 1.8.7 (2009-08-01) for LINUX_64 OpenGL,
CUDA<http://www.ks.uiuc.edu/Development/Download/download.cgi?UserID=&AccessCode=&ArchiveID=983>).

3. Not sure about the VRPN version, but it's vrpn-icm

We connected the Falcon to the machine through VRPN without problem. The IMD
is runing okay. The VMDSensor file looks like this:

# VMD configuration to use a Novint Falcon as a VRPN tracker and force
feedback device.
device falcon0 vrpntracker://localhost/Tracker0
device fbuttons0 vrpnbuttons://localhost/Tracker0
device ffeedback0 vrpnfeedback://localhost/Tracker0
To connect the Falcon to the IMD, a tug tool needs to be created and then
three devices falcon0, fbuttons0, and ffeedback0 need to be assigned to the
tug tool. However, whenever we tried to create a tug tool, following errors
came out.

Anyone knows what might go wrong? I really appreciate it!
