According to this post on skype forum, the native 64 bit version will not come at the nearest time.
Regarding the suggestion to install i586 rpm with yast - yast did try to resolve dependencies, but it suggested to install 32 bit version of qt instead of 64 bit version which I already have installed, which is not acceptable.
The best way I have found to run skype on 64bit without rubbishing my system with 32 bit packages, was the following:
1. Download static skype version from skype.com site.
2. Unpack it - if now to run it, it will still complain that it misses libsigc-2.0.so.0 - though this lib is installed on my system, it wants 32 bit version of it. Qt is fine with static skype.
3. Download binary 32 bit libsigc++20 library - I have taken it from here ftp://fr.rpmfind.net/linux/fedora/ex....17-1.i386.rpm
4. Do not install libsigc...rpm - open it in some packager and extract libsigc-2.0.so.0.0.0 file from it.
5. Put it to the unpacked skype directory (skype_static-220.127.116.11) and rename to libsigc-2.0.so.0
6. Run skype.
