Comment 9 for bug 261380

It isn't necessary to update to Jaunty just to check this. It would be enough to get a library package unpacked so you can objdump it, and to compare the file name mentioned there with those from the dbg package file list. "dbg -x" would do the former, while the latter might be possible without even downloading the package itself.

Unfortunately it looks like the 1ubuntu1 build is too brand new. The links to the binary packages on the page you referred to lead to launchpad error pages, and packages.ubuntu.com is still taking about version 0ubuntu1. So if you can lay your hand on these packages, you might try this out, but I didn't manage to yet.
