Ruby is now installed here:
/shared/common/ruby-18.7/ruby
Rubygems is installed here:
/shared/common/rubygems
I created a bin directory to link to their various executable files:
/shared/common/bin
So now people just need to append this line to their .bashrc:
export PATH=$PATH:/shared/common/bin
Please comment concerns or follow-ups on this bug:
Thanks for reading,
