On FreeBSD, I get the following, when I try to load package R2jags:

Lade nötiges Paket: rjags
Lade nötiges Paket: coda
Linked to JAGS 4.0.0
Loaded modules: basemod,bugs
Attache Paket: ‘R2jags’
The following object is masked from ‘package:coda’:

So, in principle, it should work on Unix alike platforms.

I suggest, your next step should be to rebuild packages coda, basemod
and bugs, and of course, package R2jags_0.5-7?

Sorry, no other clue so far.
