[CentOS] yum "transaction check error"

I need help resolving a "transaction check error" when trying to 'yum install 
gtk2-devel' on a CentOS 4.2 x86_64 system.  I have a feeling this is due to 
having both x86_64 and i386 libs?

# yum list installed xorg-x11-libs
Installed Packages
xorg-x11-libs.x86_64                     6.8.2-1.EL.13.20       installed
xorg-x11-libs.i386                       6.8.2-1.EL.13.20       installed

Is there any way around this?  Do I need to erase xorg-x11-libs.i386 (and the 
gobs of packages that depend on it)?

Below is full output from yum install command, thanks!
