Many, many thanks to Bob Brose for continuing to build Mozilla products for Linux PPC. That said, I just tried to run Thunderbird 1.0.2 on my YDL 3.0.1 system. I got the following error: ./thunderbird-bin: relocation error: ./thunderbird-bin: undefined symbol: gdk_threads_lock Ideas? Suggestions? Is there some new library or library version that I'm missing?
