Update:

The new beta doesn't come with a G5 built for MorphOS, unfortunately:

"as it seems there is no official compiler with G5 support yet in the MorphOS SDK and it is rather complicated and unreliable to compile any source for that processor. Until this situation is improved the G5 version for MorphOS won't be available from the beta binaries."

"The compiling for G5 is still not resolved for MorphOS, no G5-optimized binary again, sorry guys. If you could tell me how can I (easily) compile the files for G5 on my iBook then I give it a go, I promise."

I am curios. Does Fab have his own gcc on Morphos or is he using cross compiling?
