You have a local version of libxrender1 installed for amd64 that's newer than the version in the Ubuntu archive, and the corresponding i386 package is not available.

From the version number, I assume you installed this from a ppa, but that you did so by downloading the package manually instead of by adding the ppa to your apt sources.

If you need to keep this package installed (because it fixes some bug that affects your system when using the released version?), you can add the ppa to your system config using the 'add-apt-repository' command. Otherwise, you should probably downgrade to the released version by running:

 sudo apt-get install libxrender1/oneiric

after downgrading libxrender, you should be able to install skype with 'sudo apt-get install skype:i386'.
