Attempting to install a 32 bit GTK2 libs on a 64 bit host can lead to strange dependency loops.

sudo urpmi libgdk-x11-2.0.so.0
The following packages can't be installed because they depend on packages
that are older than the installed ones:
libpango1.0_0-1.30.0-1.mga2
libgtk+-x11-2.0_0-2.24.10-4.mga2

In order to satisfy the 'xfce4-notifyd|xfce4-notifyd|xfce4-notifyd|xfce4-notifyd|notification-daemon|notification-daemon|xfce4-notifyd|notification-daemon|notification-daemon|xfce4-notifyd|notification-daemon|xfce4-notifyd' dependency, one of the following packages is needed:
 1- notification-daemon-0.7.4-1.mga2.x86_64: Notification Daemon (to upgrade)
 2- xfce4-notifyd-0.2.2-2.mga2.x86_64: Notification daemon for Xfce desktop environment (to upgrade)

It can result in devel packages conficting against one another.

All you have to do is be on a 64 bit host and attempt to install GTK2.
