As I said in the original post it works reasonably well on Debian (not for all libraries since only a subset is available, but all the basic ones) -- there were shakeups in Ubuntu which were messing with the multilib support, so I don't know the current status but I can check at work tomorrow (probably not for something as ancient as natty, though).

Right.  I still haven't gotten bugged within Debian to ensure that my
packages are build.  More and more 'core' libraries seem to appear in
multi-arch mode though.  We're getting there, slowly but surely.

I usually disagree with statements like this. Debian does this pretty reliably, and
I also update all my Ubuntu machines within a few weeks of the releases. And
Ubuntu 12.04 has been a rather smooth upgrade on all of them. But if you're
several releases behind, maybe you did more 'funky' stuff you now need to

Dirk, who thinks this should have been on r-sig-debian all along
