Can you email the full compile line so we can see what it looks like?  

When NCL (and NCAR Graphics) version 6.1.0 was released in October 2012, we introduced a dependency on cairo graphics for the low-level graphics code, and hence you need to link some additional libraries when compiling C or Fortran code that depends on NCAR Graphics. One of these libraries is called "cairo" which will probably take care of the issues below, but cairo has other dependencies so there are more libraries you need to link.

For information on this, please see:
