Heather,

Check to see that you don't have any files or directories in your path
or working directory called "gplt" which wouold cause an attempt to launch
that gempak program to fail. Try typing "which gplt" to make sure that
the correct $GEMEXE/gplt is being found in your path.

Are you able to run GUI processes such as ntl, nmap2, nwx? Since these
do not fork a gplt process, that would determine if the problem is gplt related.

Since you seem to say that it was working until some point, then it
sounds like something in the file system, either local or nfs is confusing 
your PATH to $GEMEXE executables.
