The problem is the linkage with your g++ stdlib. Different versions of Ubuntu have different versions of g++ stdlib. You cant always copy binaries from one to the other.

I encountered the same problem using the latest update today (R 3.3.1 for MacOS X). My R installation seemed to crash after updating it. My solution was simply to remove the lib directories from the file system and reinstall R:

rm -rf /Users/johann/Library/R/3.3/library
sudo rm -rf Library/Frameworks/R.framework/Versions/3.3/Resources/library
