* installing *source* package ‘nloptr’ ...
somehow it does not ask for gcc which I did install following http://mran.revolutionanalytics.com/documents/rro/installation/#revorinst-lin
Solution
This is a problem with our install.sh script not installing the package named g++ for you.
If you run this command on your system
sudo apt-get install g++
and then re-install RRO, you should ready to go.
