francois,
good news, yesterday i downloaded a couple different files and decoded to
netcdf, it worked w/o errors. i'll attach the cdl used. i agree the
netcdf and udunits libraries need to be rebuilt. a word of
advice on building on linux, do
% setenv CC gcc
before running configure to get the compiler flags correct.
