[ncl-install] Installing ncarg on OS X 10.9 with ifort

[Rick Brownrigg]

Hi Dave,

On the issue of M_PI, on my linux machine, it resides in math.h and would
be gcc's. Its guarded by preprocessor conditionals:

#if defined __USE_BSD || defined __USE_XOPEN
....
# define M_PI           3.14159265358979323846  /* pi */
....
#endif

As Dave Brown's reply indicated, there's probably some compiler option that
will enable it.

As for the link errors -- I really don't know what to suggest. I have zero
experience with ifort.  The undefined symbol "_ggkwdr_" is a bit of C--code
coming out of libncarg_gks.

Wish I could be of more help...
Rick
