R help - Aug 2010 - Problems loading rjags in R 2.11.0 under OS X 10.5.8

Dear list members,
I'm trying to use JAGS 2.1.0 from within R but every time I try to load the
rjags package I receive the following message:

Loading required package: coda
Loading required package: lattice
Error : .onLoad failed in loadNamespace() for 'rjags', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared library
'/Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so':
 
dlopen(/Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so,
10): Library not loaded: /usr/local/lib/libjags.1.dylib
  Referenced from:
/Library/Frameworks/R.framework/Resources/library/rjags/libs/i386/rjags.so
  Reason: image not found
Error: package/namespace load failed for 'rjags'

Any help regarding how to solve this problem would be greatly appreciated.
Many thanks in advance,
Ruben

  Just a guess: are you using an up-to-date version of R?
  I think you might be picking up an older version of rjags
which in turn is looking for an older version of JAGS ...
Please update, if you can -- if not, or if that's going to be
a major hassle, at least post the results of sessionInfo()

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?
