Dominique Michel (upstream of alsaplayer if I don't remember wrong) reported at http://bugs.gentoo.org/383643 that raptor2.h include should be used instead of raptor.h
It seems that raptor.h is only there for compability reasons
I'm currently without my development machine, due to some problems, and I'm unable to verify the data so please look into it.
Thanks, Samuli Suominen
