[netCDF #GWM-519484]: netcdf ar build default problem



Hello Adam,

This error doesn't appear to be related to netCDF directly; libdyn3d.a is not a 
netCDF library.  Additionally, the `make.log` file provided does not reflect 
any error when compiling netCDF.  Is there perhaps a way to get a newer 
libdyn3d.a? I've searched around for a bit regarding libdyn3d, but have not 
turned up anything particularly useful.  

For what it's worth, the warnings are probably safe to ignore, unless they are 
manifesting in a specific error that isn't reported in your email.  It is 
inconvenient, but I'm afraid I don't have a better solution at this point. 

If it *is* manifesting a specific netCDF error, please feel free to follow up 
with me with specifics and I will see what I can figure out.
