Application test OS X (Qt)

I need someone to compile and test a software based on Qt, to do that you need to meet the following requirements : * Mac OS X 10.7 Lion * Qt Creator * XCode * mplayer, mpg123 and cdparanoia installed in /opt/local/bin/ (you can install it easily/automatically using macports) * Some audio files * MSN or IRC (to talk) Note : this is a little sub project, i have actually to resolve a bug, and i actually can pay you 10$ when this bug get resolved and 10$ at the end of the project, this may take some days...but your work is very very simple. You don't have to write any code, but you have to just follow my instructions and send me debugging information. After resolving such bug i may have need of further testing, until my project finish, but it's improbable since this is the latest remaining bug. For any doubt, please ask before to bid.
