The sources supplied by gentoo donot compile (Makefile not correct in xine-ui/src /xitk/ ). When corrected by hand it compiles but does not run. I tested the xine-ui-current/xine-lib-current snapshops and they work with gentoo 1.3.. So, I would suggest to distribute this version with gentoo 1.3
fear not this is fixed with the masked 0.9.10-r1 once we do a bit more testing and catch one more bug we'll release it.
