site-info is incorrect

Synopsis:

As of the ltb-wsuvr5-site-info-200514 branch, there are still problems with 'site info'. Specifically, there appear to be interactions between Apache, Passenger and using backticks in Ruby. The end result is that the command run via ruby's backticks doesn't necessarily get/see the same environment as the running process. Although the app is running as the 'autolab' user, it doesn't appear that that user's .bashrc gets sourced when the backticks are used.
