netCDF-4 files are different from netCDF-3 "classic" files, in that they use 
HDF5
as the storage layer.  NetCDF-4 alos supports an "enhanced data model", 
compression, and other new features.  It's possible that the tool you're using
would work if it is recompiled and relinked to a recent version of the netCDF-4
library, such as netCDF-4.1.3.  That's the intention if the data uses the 
"netCDF-4 classic model" format.
