To fix the constraint problem in the 4.1.3 netcdf distribution. Obtain the following tar file: http://www.unidata.ucar.edu/staff/dmh/netcdf-4.1.3-fix.tar and replace the files in the distribution with those in the tar file. Let me know if you are still having problems. However, there is still a performance bug that will cause problems with large variables (notably server failures or timeouts). =Dennis Heimbigner Unidata
