Installing scl devtoolset on CentOS6<\/a><\/p>\n
Create under \/etc\/profile.d with the following content\uff08example for devtoolset-4 collection\uff09and enable scl's devtoolset for users after reboot. So you can install Passenger by `passenger-install-apache2-module` or install gems which need native build with Capistrano.<\/p>\n
