Howdy Michael! As you might have guessed, you have us a bit stumped with your netCDF install problem! I wonder if you would try the latest beta release? Get it from here: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf-beta.tar.gz This builds without problems for me on our Macintosh (as does the 3.6.1 release you are already using), but it is quite different from 3.6.1. If this doesn't work, then the problem is probably something with your machine... Thanks!
