Sounds like ngmx wasn't installed, probably because it was disabled in 
configure, either manually or because you didn't have the requisite 
libraries. Try your configure command again and read closely for motif, 
lesstif or X related messages. ngmx is the only GROMACS utility that 
needs them, so that's why this is the mostly likely cause of the 
problem. It wouldn't be flagged as an error, because ngmx is quite 
superfluous for most people, and a lot of compute-only systems are set 
up without X, and so ngmx can't be compiled...

Also, next time you change topic, please start a new email and use a 
relevant subject. This will avoid situations such as the one person with 
the answer to your question discarding it unread because they have no 
interest in the topic of the old subject line.
