I'm trying to write up a *.spec file to package up the phonon-mplayer backend, but every time I compile it, I keep getting an undefined interface error even though I have phonon-devel installed and mplayer. For now, I'm inspecting the *.src.rpm for Ark Linux on how they managed to compile it, but it isn't much different from what I was trying to write up.
Sorry that I don't have the current *.spec file I am trying to get working, as I typed this up not on my home computer. However, I can link you to the *.src.rpm that I found that they used (since the binary magically works on PCLOS for some reason): http://ftp.heanet.ie/mirrors/arklinux/dockyard-devel/SRPMS/phonon-mplayer-1.0.0-0.20110107.1ark.src.rpm
[EDIT]: Forgot to mention that the spec in the linked src.rpm still outputs the same compile error if the instructions in them are fixed up so they are for PCLinuxOS.
[EDIT2]: Here's the output I get: http://pastebin.com/sNVGgg0U
The spec file so far (based on what's in that src rpm): http://pastebin.com/mJPbdnCi
