Running the prebuilt JUCE demo from the web site gives me the following error in the console log:
dyld: Library not loaded: /usr/local/lib/libogg.0.dylib
Referenced from: /Volumes/JuceDemo/jucedemo.app/Contents/MacOS/jucedemo
Reason: image not found
The demo then quits.
This is only on the Mac version - the Windows version runs fine.
