Pete,

The USE_GFORTRAN=1 flag is only set for compiling the package by telling
which Makinc.linux64_xxxxxx file to use.

This flag has no effect for the runtime environment.

The na programs can be linked directly to the gplt, but it does produce
a much larger executable, so I don't do it, but it is possible.

It would help to know at what point you see a segmentation fault, eg in 
launching, or
somewhere within running the program, and what your input source is. The problem
you are describing could be a Tab" character within a FORMAT statement within 
the
code that gfortran doesn't handle and I didn't catch in the distribution.
Can you provide the text output of your session and show me the error?

Thanks,

Steve Chiswell
