Skype is provided pre-packaged for openSUSE for 32 bit systems. However the RPM can be used without difficulty also on 64 bit systems, since openSUSE transparently manages bi-architecture packages. Unfortunately the 32 bit RPM does not install all the dependencies it needs to work correctly, and you have to fix them by hand as follows:
- Install the skype rpm by typing in a root terminal: rpm -Uvh skype-220.127.116.11-suse.i586.rpm
- Open YaST software installer
- Search and select the following packages
- Accept the additional dependencies proposed by the installer and proceed with the installation
At this point, you should be able to run skype without any difficulty.
