Hmm.. I can't figure out to get passed this - tried varies ways in Xcode, but no luck so far. Should I perhaps download and install Qt directly from the source rather than using the version coming with Gecode?

Great. I will await the new builds. And until then I'll do without Qt.

:-§ That was a creepy one! And I had to pick just that file... Removing 
the character did the trick. Maybe you should fix that in the next build 
as well.

And in MGP section 2.3.2 there's some minor issues:
1) Correct the command line example - the last line should at least end 
with send-more-money.o
2) Update the Xcode description regarding adding frameworks

Thanks again for your help!
