Hello,

R is not finding the netcdf library that you compiled and, presumably,
installed.  If you installed the netcdf library in a standard place, such
as /usr/local/lib, it would probably be found by default.  If you don't
want to (or can't) install in a standard location, the easiest fix is to
add the location where you installed the netcdf library to your
LD_LIBRARY_PATH environmental variable.  For example, if the netcdf libary
is in /opt/sw/netcdf/lib, then you'd add that directory to
LD_LIBRARY_PATH.

Hope that helps,
