Hi Stephen,
you should try lattest CAVER which could be downloaded from
http://www.caver.cz
before installing it via Pymol plugin menu, you should to open
caver-3.0-1.py and find here
CAVER3_LOCATION = "directory/where/caver3/is/located"
and modify this on your path providing it to the jar file
I would be interested in just how the problem has been solved!
I just installed caver v-2.1.2 in the 64 bit Debian Testing with PyMOL
v-1.6.0.0 compiled from the latest svn and functioning perfectly on my
system.
Carver installed from the PyMOL wicki via the PyMOL Plugin Manager
