There are other ways, but if you have (or can install) libgd and 
freetype, you may consider using the GDD device - it can produce jpeg, 
png and gif on unix w/o the need of X11. The nice thing about it is 
speed (it doesn't use any external process) and that it uses 
anti-aliasing of both text and lines. It was designed specifically for 
graphics-on-demand on web servers.

Currenly GDD is not on CRAN (yet), but you can get it from
Just make sure that you have libgd and freetype (if you any problems or 
suggestions, please drop me a line).

There are other methods, too, like the bitmap device, which uses gs 
(AFAICS), or you can run virtual X11 to satisfy the devices that 
require X11.
