Yes, that's probably correct. I'll modify (if possible) the dependencies
in planetccrma-core to take this into account, that is require both
architectures in the Requires:. I don't know if rpm accepts that at

That one is a surprise...

Correct, I did not know that it was built for both architectures _and_
installed by default. I wonder what requires the i386 version?

Could you do, for example:

  yum remove jack-audio-connection-kit.i386

and of course say "n" when asked... but note down which packages are
going to be erased if you remove that guy?

(later: looks like arts.i386 and fluidsynth-libs.i386 are the only ones
requiring a i386 version...)

Hmmm, I don't have an answer to that. 

I had imagined that multiarchitecture packages, when installed together,
would not share binaries, after all that's what multiple architectures
are for. I'll try to learn more about this...
