Comment 1 for bug 744908

Matthias has uploaded a workaround for this by way of eglibc, to add compat symlinks back to /usr/lib/*.o in the -dev package. This will probably not be accepted until after beta; in the meantime you can grab the source package from https://launchpad.net/ubuntu/natty/+queue?queue_state=1&queue_text=eglibc if you want to test it.
