[R-SIG-Mac] cannot load rjags package on Mac

[Simon Urbanek]

Wei,

the CRAN binary uses JAGS 2.x so you'll have to download and install JAGS 2.2.0.

Currently, JAGS 3.x is unsupported because we there is no official JAGS 3.x binary for ppc anymore which is a requirement for rjags to be built on CRAN.

I will have a look at JAGS later today to see if there is hope to have JAGS shipped with the package.

Cheers,
Simon
