Steve, Thanks for you advice. GEMPAK did locate all the necessary files in /opt/SUNWspro, but the machine we're using is using Solaris 2.6. So, after downloading the appendix library files, dcgrib2 now works (had to eliminate reference to SUNWspro in the library path...otherwise, it kept ignoring the new library directory...regardless of ordering in the .cshrc file). I guess I was lucky that earlier GEMPAK versions were compatible with Solaris 2.6.
