I've got a mac mini with centos 4 installed and wonder how "easy" it would be to get the srpms and compile the sme additions on ppc. It would be so cool to get sme running on my little mac!
I agree. It would be cool, and I've thought of having a go myself.
Has anyone got ayd advice? Am I stupid to think this is even possible without some major graft?
I think 'major graft' would be reasonable description. Nothing like impossible, but even if you have good experience at rebuilding and modifying RPMs, it'll be a significant task.
If you want to take it on, I'd strongly advise you to join the devinfo mailing list and ask for advice there whenever you hit any obstacles.
