In CFLAGS.
But you don't need to set it...

With grads or hdf? You should try make before make install.
If you have compiled HDF4 with -DHAVE_NETCDF you'll have the ncxxx
symbols renamed sd_ncxxx.

Maybe you could try the attached patch that comes from the hdf rpm
(you may need -lm for some math library functions).

Strange...

It is certainly not within the grads or hdf code themselves, these are
certainly link/install issues, but may well be within the autoconf macros
I produced...
