thanks a lot for this "real time" response.

well, no. actually I _have_ 10.4.11 installed (I somehow was sure it's 10.4.7,
still. that's probably alzheimer casting his shadow :-)).

10.5.2 is no option for me since I need a working fullscreen X11 mode.
I now checked it again both on a dual 2Ghz G5 PPC and a 1.5 GHz power book PPC G4, 
both running
10.4.11: same problem. actually, R hangs only when really plotting. so
I can first open the device with X11() and get back to the R prompt. only
when executing the `plot(1:10)' R apparently hangs and everything is as described
in my first mail.

here comes the session info:

R version 2.7.0 (2008-04-22) 


attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] micropet_1.7.0 psflib_1.0     pkc_1.1        fzrutils_1.3   roiutils_1.3  

(identical on both machines).

any hint/help really appreciated.
