I need the i686 and x86_64 versions of itcl. When I install the i686 version with yum it conflicts with the existing x86_64 version:
Transaction Check Error: package itcl-3.4-6.fc12.x86_64 (which is newer than itcl-3.4-5.fc12.i686) is already installed
I think the comparison is messed up since it is comparing files of different architectures which shouldn't matter since they need to co-exist, it seems to me.
