well analysed !

As a conclusion: I must check my spec-files to remove "Requires: openal", 
because this way I can't force the use of the packman package, as the 
openals-soft package tries to "provide: openal" and contains also a library 
with the old so-name of original openal...

So lets hope that our beloved games are still working with this mess.
Your detailed feedback is very appreciated. If things go worse, I can try to 
link openal statically and or switch to other sound-output possibilities (in 
case of funguloids: fmod)

As we build our packages in a chroot, the removal of libopenal.la is not 
possible on the fly. One possibility is to repack the package for the packman 
repo.
