As the title says, I recently ran the system updater. At the time there was 400 updates. I installed them all and everything was peachy.A few days later it showed that I had more updates. So, wanting to avoid getting to 400 updates again, I ran them. There was only 4 and they were all related to python libs. These were all level 3 updates and I installed them the day after they came out (6/25/13).I am a Ruby On Rails developer and the next day I came in and was working on a project, I went to run my rails server with the command rails s and I got this message:rails is not currently installed please run apt-get install rails to install.I then tried to run rake, cap -f deploy(capistrano), and even ruby -v and I got the same message for all of them.RubyMine (my IDE) still sees that ruby on rails is installed, and I can run my dev server though that.This is not ideal however so:How do I make my terminal see my ruby on rails installation again? 
I recently ran updates now the terminal doesn't see installed packages
linux mint;upgrade
