Description of problem:
03:29:59 : ERROR: Error in yum Transaction : Test-Transaktionsfehler: file /usr/bin/wx-config from install of wxGTK-devel-2.8.11-1.fc12.i686 conflicts with file from package wxGTK-devel-2.8.11-1.fc12.x86_64
I can´t install it.
There was a lot of clean-up in the rawhide (now F-13) package and multilib fix was one of them. I don't plan to backport it to F-12.
