[netCDF #IMK-675971]: mac os x and netcdf 4.0.1

I would like to fix this problem in the build files, but I can't quite tell 
what is going on from your email. When I build, the hdf5 library (and hdf5_hl 
library) are correctly linked in the libsrc4 directory:

/bin/sh ../libtool --tag=CC   --mode=link cc  -g -O2 -L/machine/local/lib      
-o tst_h_files tst_h_files.o libnetcdf.la -lhdf5\
_hl -lhdf5 -lz

Can you be more specific about the problem?

Thanks,

Ed
