rjags install on Ubuntu 10.04

OK. I figured it may be getting late in the LTS cycle. However, I'll be making two trips
in next 18 days, so don't want to rebuild my laptop just now. It has way too many
different tools on it that I'm using and have forgotten that they take time and bandwidth
to install. The folk who want jags runs are just going to have to wait.

Given I have tried Unity twice and Ubuntu's alternative Gnome once, I think I'll go to
Mint Mate (Ubuntu based) or else CrunchBang (debian squeeze).

You may be on your own here. I would suggest updating to something current,
and remaining current -- at least that works for me. On Ubuntu 12.04 it
just works:

There is also a numbering issue at work here.  Version 3.3-1 is supplied by Ubuntu, while
my PPA has 3-5, a newer version from Martyn, but not for Ubuntu.  For apt, 3.3 is > 3-5,
so one solution is to use synaptic to force the install of the more recent version and see
if that fixes the issue, although I would recommend upgrading Ubuntu as the first step.

Conveniently, Martyn release version 3-7 of the package Wednesday (9/18), so new versions
will be hitting the PPA shortly, as soon as I resolve the numbering issue.

Please.  R has not bearing here.

You have a package out of sorts. Worst, remove the package (here: jags, as
'dpkg -S /usr/lib/JAGS/modules-3/bugs.so' clearly tells you) and install
locally.
