I take the latter part back. I could not possibly load rjags with JAGS-3.4.0 linked.

That is a great command to have. Once the better formatted envvars with value is listed, I noticed that JAGS-3.3.0/bin is in the PATH, so that problem is also solved for my user. 

Thanks,
Jun

For your first question, try str(as.list(Sys.getenv())). I do not know the answer for the JAGS question, and I'll leave it to someone else to tell you which mailing list to use for such questions...

Is this because I don't know how to use it or something could be improved? Usually I'm not sure the exact name of a variable but want to look it up. Recently I installed rjags, with the JAGS-3.4.0's lib, include, modules information provided during compilation. When I load rjags, I was told that it linked to JAGS 3.3.0 (a package also available in my environment). This made me think there must be a variable to make that to happen. What can I do to make rjags to link to JAGS 3.4.0?
