there is more on the side of distributions, because it is more unusual to have
multi-lib Linux (originally it was used on Linux only to get 3rd party [mostly
proprietary] 32-bit binaries working on 64-bit systems and that is now less of
an issue). 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).
I upgraded Ubuntu to 12.04 and installation of most packages work, so
the issue must have been due to missing system packages as Simon suggested.
I still have an issue with RCurl though. It appeared when wanting to
install 'devtools' but seems to be more general:
```

** package ‘devtools’ successfully unpacked and MD5 sums checked
** R
** inst
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
*** arch - amd64
*** arch - i386

Making packages.html ... done
Warning message:

```
I noticed that when installing RCurl, it seems to only compile for the
current session's architecture, while other packages build on both
architectures, whether called from a 32 or 64 bits session.
So RCurl is then typically only available on one architecture, and any
install depending on it would fail.
Is anybody able to reproduce this?
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
consider.
Ok, I should have been stayed away from such a general statement :)
While the upgrade or fresh install+restore packages takes a couple of
hours, I often spend the rest of the day to get the environment
identical to what I had before upgrading. Nothing too funky: re-figure
out things like how I to get through an annoying proxy, and deal with
surprises in new versions of some apps, etc..
For sure my upgrade workflow is far from optimal. Upgrades are
eventually just a -- frustrating -- day :)
