Re: cannot find -lexpat

Please see our release notes for V6.1.0, which indicates some changes to compiling NCAR Graphics codes.

http://www.ncl.ucar.edu/prev_releases.shtml#CompilationChanges6.1.0

If you are just using "ncl", then you don't need to worry about installing these libraries, unless the "ncl" executable starts complaining about dependencies (it shouldn't do this).
