I’ve been looking into this for the last three weeks. First it was an issue with JavaCore, then it was an issue some PPC tags, the third time I’m not ever sure I know what it was. I suspect that it was those PPC tags again. The last bug for JavaScriptCore took developers several weeks to get to fix the PPC bug. Its difficult being PPC sometimes, I tried installing Amaya a couple days ago only to find that it has some x86 assembly code in it.
Well last night I was able to compile webkitgtk-31535 from sunrise. So now I have a huge choice to make as gecko 1.9 is nearing release.
