For some reason, my builds of R (OS X 10.4.4, gcc 3.3) on our G5
machines
aren't picking up these libraries (as evidenced by the output of the
capabilities() command), even though they exist and check out
as OK in config.log.
However, the G4 builds include both. The only difference I see in
the configurations
are the use of G5-specific optimization flags on the G5s:
CFLAGS='-mcpu=970 -mtune=970 -mpowerpc64 -mpowerpc-gpopt'
Any suggestions appreciated.

Ah, it just hit me - do you have X11 running at all? Bitmap support requires you to have X11 server running, because that's the way R creates bitmaps. The output of "capabilities" is dynamic, i.e. if your DISPLAY is not set or there is no X11 running, R will disable both X11 and bitmap support. Cheers, Simon
