I'm attempting to set up a hosting server for my rails app. They have a tutorial and very specific way of setting up the environment. I've followed it to the best of my ability and either I've made a mistake or they have. I've substituted the appropriate username for USERNAME

I've set up my .bash_profile like they state:

# START
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

PATH=$HOME/.gems/bin:$HOME/bin:$PATH

GEM_HOME=$HOME/.gems
GEM_PATH=$HOME/.gems:/usr/lib/ruby/gems/1.8

export PATH GEM_HOME GEM_PATH
# END

Then I'm instructed to run: source ~/.bash_profile

Then gem install rails

Then they say to add this line to .bash_profile before the export statement, which I don't understand because it's already in there leading me to believe it's a typo:

PATH=$HOME/.gems/bin/:$HOME/bin:$PATH

Then again run source ~/.bash_profile

Then when I run which rails I should get: /home/USERNAME/.gems/bin/rails but I get /usr/bin/rails

Can anyone help me point to the right direction? Thanks.

Also here's the output of gem env:
