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 
  edd at max:~$

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.

| apt-get autoremove
| 
| then reinstalled R, then rjags (the Michael Rutter PPA is in my sources list), i.e.,
| 
| apt-get install r-base-dev
| apt-get install rjags
| 
| (I used the dev to make sure I got some of the tools etc.)
| 
| No joy.
| 
| On crunchbang stattler linux (under VirtualBox), things loaded fine. I haven't tried
