[R] Problems loading rjags in R 2.11.0 under OS X 10.5.8

[Ruben Garcia Berasategui]

dear Professor Ripley,
thank you very much for your prompt reply. You are absolutely right. I didn't have the latest version installed although I used the command: install.packages("rjags").
Apparently, you only get the latest version of packages if you have the most up to date version of R, which is not my case. Please correct me if I'm mistaken.
I just ended up installing rjags 2.1.0-6 manually from the terminal and everything is working fine now.
Regards,
Ruben

Which version of 'the rjags package' and where did you get it from?
I have 2.1.0-6, installed as a binary from CRAN, and I see

tystie% otool -L rjags.so
rjags.so:
 	rjags.so (compatibility version 0.0.0, current version 0.0.0)
 	/usr/local/lib/libjags.2.dylib (compatibility version 3.0.0, current version 3.1.0)

so that is not the version you have (which is looking for 
/usr/local/lib/libjags.1.dylib).

My guess is that you have rjags_1.0.x.

Re-install rjags, maybe via update.packages() or the Package Installer 
menu item if you use R.app?
