Mike,

You can obtain the Solaris binary for Xvfb from various locations
to create the virtual frame buffer:
http://www.unidata.ucar.edu/projects/coohl/mhonarc/MailArchives/gempak/msg03323.html

You can also use the non-X11 gif driver "gif" under GEMPAK 5.6A
(called "gif2" for GEMPAK 5.6). The hardware fonts available
from the X server using the "gf" driver will look better however.
