This might help - we found that we needed to install the MS TT fonts and
make sure that GDD can find them, as per the README. :

Sorry, my laziness. GDD was unable to find any fonts. After I installed
the MS TT fonts and set their location as per the GDD README, it worked
perfectly with both old-style R graphics and lattice graphics. The
output looks very nice indeed. We'll do a bit more testing (and let you
know if we find any problems), but it looks like we can at last drop the
requirement for Xvfb when using R in a Web application. Great work! From
our point of view, GDD solves one the biggest problem with R for Web
applications.
