Thanks again, Marco.  Unfortunately, still no joy after redoing you
rebaseall & peflagsall statements and rebooting.  I got the same error
as before:

octave:1> plot(1:5,1:5)
      9 [main] octave-3.4.2 5952 child_info_fork::abort: address space needed by
      'cellfun.oct' (00570000) is already occupied
