Answer 1

OSX 10.8.2, ruby 1.9.3p125

None of the above worked for me... I got tired of trying to find the right gem for my environment, so I just soft linked to the g++ target this things was missing:

sudo ln -s `which g++` /usr/bin/g++-4.2

Not as helpfully for remote deployments, but get the job done on my workstation.
