Quick tip for everyone who wants to install Skype on Fedora-14 64 bit.
Apart from the regular dependencies, I had to install the following packages in order to satisfy 32-bit compat dependencies of Skype. Apparently these packages are no longer installed by default. Run this as root:
yum install libXv.i686 libXss.i686l libXScrnSaver.i686 qt.i686 qt-x11.i686
