@KaKaRoTo: It looks to me like there is a problem in the compiled version of TkCxImage, couldn't it be similar to the problem we had with windows + VC2008?
@Jose: Run amsn from a terminal, it will give more informations. But KaKaRoTo already pointed to the same issue reported by someone else and it doesn't help very much

Send me your mac, I will fix it
