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:
R> library(rjags)
Loading required package: coda
Loading required package: lattice
linking to JAGS 3.2.0
module basemod loaded
module bugs loaded
R>
Using
edd at max:~$ COLUMNS=76 dpkg -l | grep jags
ii jags 3.2.0-1precise Just Another Gibbs Sampler for Bayesian MCMC
ii r-cran-rjags 3.3-1 R interface to the JAGS Bayesian statistics

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.

i.e.,
|
| apt-get install r-base-dev
| apt-get install rjags
|
