That's the right one.

It needs a VRML viewer, whose location is defined by the environment 
variable VRMLVIEWER.

VMD is not a VRML viewer! For generalized visualiztion with VMD, use the 
module Scientific.Visualization.VMD instead of 
Scientific.Visualization.VRML. The interface is the same as much as 

Moreover, on the Mac, you need a small shell script to be able to run VMD 
from another program, due to the way VMD is packaged for the Mac. This shell 
script is then pointed to by PDBVIEWER. 

I am not using my Mac at the moment so I can't send the script, but I will 
do so later (assuming I don't forget...).
