Looks like curl support is added to netcdf by enabling the dap variant. It's on 
by default so you should already have it, unless you explicitly disabled it.

My copy of netcdf is also already linking with libz. I'm not sure if that's 
because of curl (which itself depends on libz) or for other reasons. Maybe 
netcdf needs to have a zlib dependency added.

My copy of netcdf is not linked with libdl and I don't see a way in the 
portfile to do that. What would linking with libdl accomplish?

I'm trying to build a code that requires netCDF and hdf5. I keep getting
the errors shown in the attached log file. It appears to me there are
issues with lcurl and lz.

Re: Linking curl, lz, and ldl to netCDF

[Stephen J. Butler]

Your project is linking against the static versions of netCDF and hdf5. I
believe the proper solution to your problem is adding -lcurl, -lz, and -ldl
to the linker flags of your project.
