Yes, since OS X 10.5 Apple dropped support for AWT on the main thread,  
so essentially you cannot use any graphics classes in R on OS X 10.5  
since R is single-threaded. They work in JGR, though.

This is a bit problematic for tests and I don't have a good solution.  
I have a hack that you're welcome to use -- when checking packages on  
OS X 10.5 we set NOAWT=1 so you could make your graphics tests  
conditional on

if (!nzchar(Sys.getenv("NOAWT"))) {

## AWT/Swing tests here

}

It's not pretty but that's all I can offer at the moment .. Ideally  
Apple would fix that issue but ...

Cheers,
Simon
