OK.  You should be able to build ldm-mcidas linking against the version
of netCDF built with McIDAS.

I am not suprised by this.

I believe that you need to grab the LDM 3.5.1 beta (or above) to be
able to build the C++ interface using GCC 3+ (RedHat 8.0 comes with
such a version of GCC).

That's right, my recommendations for building McIDAS is to define CXX
to be blank so the C++ interface will not be built (McIDAS doesn't need
that interface, so why build it).

I am at the AMS show right now, so I have to run...
