That is the most recent official version. You can turn on the large file
support at the compilation stage, but configure does it by default if
the OS supports it. I don't know about the rpms.

It looks like a 2Gb problem still. Is this just ngmx, or also other
programs? By the way, using .xtc will save you a factor of three in size
for the trajectory.

And please do send your questions to the gmx-users list....
