The netCDF install is a little hard to find on the Unidata web site, but
once you download it, it is relatively easy to install.
Before doing so, you need to install the XCode development tools from
Apple, because you do need the C compiler.
You can find the install files here
http://www.unidata.ucar.edu/software/netcdf/
There is a README file in the installation that gives the necessary
commands.
You need to be an administrator to install the library.

You don't really need to install the netCDF library to use netCDF in
IDL, but the ncdump routine is extremely handy for viewing the contents
of a file before writing the IDL code to read it.
