complaints about fonts on MacOS 10.9

[Ben Abbott]

When running the gui (hg id is 2d3b1037fd12 tip @) on Mac OS 10.9, the text 
below shows up at startup.

2013-12-02 22:27:14.530 octave-gui[51697:d07] CoreText performance note: Client 
called CTFontCreateWithName() using name "Courier New" and got font with 
PostScript name "CourierNewPSMT". For best performance, only use PostScript 
names when calling this API.
2013-12-02 22:27:14.530 octave-gui[51697:d07] CoreText performance note: Set a 
breakpoint on CTFontLogSuboptimalRequest to debug.

PostScript name "CourierNewPSMT". For best performance, only use PostScript

name "Menlo-Regular". For best performance, only use PostScript names when 
calling this API.

Is anyone else seeing this on other OSes?
