I met someone who was able to install mesa-amber on his MDD G4. He had to therefore patch the mesa-amber source and rebuild it. There is a little trick to get it to work alongside default amber. He told me that he got openGL to work with the r200 driver for the very old Radeon 9000 pro (I have seen proof). If this is the case, then you can just install mesa-amber next to the latest amber and make the system upgrade other packages (like the poster complaining about sdl2 packages).
If I have more information I will publish it here and on my site.

Just to be clear, posting that some packages appear to have issues, ISN'T complaining. It's reporting issues. Ones that I never fully got to the bottom of. Problem is, while I've been a software engineer for the last 30 years, that doesn't magically give me in-depth knowledge of endian issues and graphics APIs. Java is very different to dealing with endian issues in C/C++ APIs so I'm limited in how I can contribute here. This also applies to the thread about Chimera too.

On another note, the developer who makes this all work is asking for help. He recently added code to mesa for r300 support. He needs hardware to test, especially G5 with r3xx cards. See Paulie889's message here:

I never meant to say complaining, I meant reporting, sorry for the misunderstanding: bad choice of words.

All good - I just feel frustrated that I can't help when I feel like I should be able to!
