Install pssac2

Hi,

Thanks for providing such great documentation. May I ask how to fix a problem that I encountered when installing pssac2? Would appreciate any input.

I was following your post on installing pssac2, but during the step of configuration, an error popped out saying "NetCDF library not found"

I attach the terminal displays below:
