You can rebuild the package on your own if you don't want to wait. Just copy the SLKBUILD from /usr/src/mpd-X.X.X to a temp directory and run "slkbuild -X" as root there. This should create a package.
New build here (3ab). It would be great if somebody could test this build (more thorougly) and push it to the repo instead of me. ATM I don't have the time/nerve for it.
It is a mpd problem. It cannot find the correct shared lib. Using third party repos is not much of use here.
A quick fix would be: cd /usr/lib (or lib64)
ln -s libmpcdec.so libmpcdec.so.5
Sorry, I didn't manage to upload it anymore and I'm on holiday from tomorrow on. It's in the bugtracker though.
Meanwhile, I've found a problem with dvdauthor, but that one has to wait until after ...
