Hi Doug,

You are linking against a version of NCAR Graphics/NCL that was built
with the g95 compiler, and hence it is referencing some g95 system
routines ("_g95_st_read_done" is one).

You have a few options:

  - You can install g95 (there are binaries available), and then link
in the "f95" library that comes with it.

To download: http://g95.org/downloads.shtml

Scroll down to the stable version, 0.91, and get either the "x86 OSX"
or "PowerPC OSX" version, depending on what kind of system you have.
("uname -a" will give you this info.)

  - You can build NCAR Graphics from source code, using your g77
compiler.

I think the first option might be easier!
