I tried a fresh install of 12.04.1, and I don't get the same error with ia32-libs:
$ sudo apt-get install ia32-libs
[sudo] password for ubuntu:
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following extra packages will be installed:
bluez-alsa:i386 esound-common gcc-4.6-base:i386 glib-networking
glib-networking:i386 glib-networking-common glib-networking-services
(big list of packages....)
Also, of note, adding the ia32-libs dependency would increase tarball size by about 70 MB.
Which version of Ubuntu are you running this on?
