So VirtualGL's lib path isn't there, but I'm reminded that vglrun works 
a little differently than how I usually launch VirtualGL; it expects 
librrfaker.so to be in the lib path.  A simple way to ensure they're in 
the lib path is to run:

LD_PRELOAD=librrfaker.so ls

If the command fails to run (can't find librrfaker.so) then the issue is 
with library path setup on your box.  If it works then we'll probably 
need to see the ld.log output.

I think you also ran with vglrun with +tr right? The script died because 
VGL's trace logs were captured in some of the scripts commands.

When using the +tr command with a script you pretty-well *must* specify 
VGL_LOG=vgl.log  to prevent the trace output from confusing any commands 
in the script that are capturing output (since all the scripts commands 
get the faker loaded too).

If you run again with VGL_LOG and the LD_DEBUG variables set then 
perhaps vgl.log and ld.log will tell us something useful.

Please zip the logs to avoid any problem with the mailing list blocking 
things too large.
