[netCDF #YYB-743440]: Question about netcdf version and libnetcdf*

Hello Ananya,

The reason the number changed is due to changes in the libnetcdf API/ABI 
between versions 4.3.3.1 and 4.4.1.  

I'm not familiar with macports any longer (I switched to homebrew some time 
ago); you may have to reinstall WRF. When linking, it should find and link 
against the newer libnetcdf.11.dylib.  You may also contact the WRF team for 
any suggestions they may have.  

Alternatively, it looks like there is a way to use macports to explicitly 
install an older version of a package.  You may be able to use this to 
reinstall netCDF 4.3.3.1.  While I cannot test this method myself, you can find 
instructions here:

* https://trac.macports.org/wiki/howto/InstallingOlderPort

I hope this information helps,

-Ward
