[R] Producing png plot in batch mode

[Prof Brian Ripley]

The advice in the posting guide was to ask the package maintainer (Cc:ed 
here).  Please report what he had to say, as it would be helpful to the 
rest of us.

Note that the src/Makevars.in has

# we need to add JNI specific stuff here
ifdef DEBUG
   PKG_CFLAGS+=-DJGD_DEBUG
endif

which is GNU-make specific, so you could just delete those three lines and 
try again (or use GNU make).
