[ncl-install] trouble compiling NCAR graphics on new Mac OSX machine

[Ronald L. Gilliland]

Hi Mary,

    As usual your roughly every five years advice to me has been  
excellent.
    I'm now able to compile a simple Fortran program with gfortran
calling NCAR graphics, and have it generate a metafile that properly
displays.

    A residual concern, that I now notice happens even with a run
of the test 'ncargex cpex08'  is that several lines of warning result:
(similar lines follow from my fortran compile, although both cpex08
and my fortran executable seen to do the right thing)

% ncargex cpex08

NCAR Graphics Fortran  Example <cpex08>

   Copying cpex08.f

   Copying cpexcc.f

Metafile file is named cpex08.ncgm.
-------------------------------------

Are the warnings something to be concerned about, or that I can  
dispense with?

Thanks,
