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

[Mary Haley]

Hi Ron,

Glad it worked.

You can safely ignore these warnings. We get them as well, and it  
appears to be a gfortran idiosyncrasy that I hope they'll fix soon.  
Notice that the warning is misleading, as it says "size 544 is is  
smaller than the real definition of size 532..."

If you google parts of this warning, you will see other software that  
has the same problem.
