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...
