Hi, it's unlikely that we'll fix this for OSX on PowerPC, but if you want to try, we'd look at a pull request. What version of OS X are you using?

[barracuda156]

10.6 PPC, but for practical purposes it can be considered 10.5 PPC, since it behaves as 10.5 and obviously lacks Intel-specific features of 10.6.
