It is probably my fault (details below) - a quick fix is to update your R.app GUI from http://r.research.att.com/

Technical details:

Recent R binaries (but only after 2.14.0 release) use @rpath to allow re-location of the R framework - it means that you can have the entire R in just one icon that you can move around as you please - just like the R.app GUI now except that the entire R is in there and no other dependencies are needed (e.g. you can just put it on a CD or thumb drive). According to Apple documentation the default fallback to @rpath includes /Library/Frameworks which is the location of the R framework when installed, so everything that worked before with absolute paths should be working with @rpath. However, it seems that for some unknown reason the R.app binaries don't fall back to the old @rpath and/or there are some issues combining absolute paths and @rpath. The most recent build of R.app include the LC_RPATH load commands set accordingly so they don't need the fallback. It is indeed startling, because the behavior that you see in Terminal, RStudio etc. is how it is supposed to behave according to Apple documentation. Before I figure out how to solve this you can simply grab more recent R.app.

Thanks,
Simon
