daniel,

please try using
export LD_ASSUME_KERNEL=2.4.20

before you start up VMD.
AFAIK, this is needed for all threaded applications,
that were compiled under an older installation. i had
this on several occasions already, also when running
32-bit x86 applications under x86_64.

john, if this is a usable workaround, perhaps you could
put something like the following into the linux specific
architecture detection code of the vmd startup script:

set kernelmajor=`uname -r | cut -c 1-1`
set kernelminor=`uname -r | cut -c 3-3`
if ( $kernelmajor == 2 && $kernelminor > 4 ) then
  setenv LD_ASSUME_KERNEL 2.4.20
endif
