grads links with hdf5-18 though it does not declare a dependency on it.

	/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 56.0.0)

Thus the port is broken due to the recent hdf5-18 upgrade which changed libhdf5's library version from 7 to 8.

r108944. Thanks.

Thanks. Sorry if my output above was confusing. I have local updates for gd2 2.1.0 and libpng 1.6.3 and had locally increased grads' revision to 1.
