If you are put into a position were a package depends on ia32-libs and you are unable to repackage it with the new binary (as detailed in: AskUbuntu - What happened to the ia32-libs package?), another option is to install the outdated binaries from the Raring repository.
WARNING: Installing old packages is bad practice!
echo "deb http://archive.ubuntu.com/ubuntu/ raring main restricted universe multiverse" >ia32-libs-raring.list
apt-get install ia32-libs
