i committed a small scons fix for osx.
besides the known bugs, it's really nice :). thanks.

some more issues:
- when the ttf file is not found it displays a message on the console
not in the repl, which is difficult to spot if you are livecoding in
fullscreen
- strange behaviour with outlines:

the problem goes away when the (hint-unlit) is commented out

best,
gabor
