A. WTF is there a chown in src_unpack(), first it wont work with usersandbox, second, its completely useless if you run as root B. Use epatch C. The src_install is one the most convulted way I've seen in a long time for that kind of stuff and I've just looked at -r4...
I just checked in cleaned up versions - do those look ok to you Olivier?
looks much better. thanks
resolving bug then
