Changed name of user directory now rails command not recognized

Changed name of user directory now rails command not recognized

I'm using OSX and I wanted to change my username, so I followed the
official Apple directions and used mv to change the name of my directory
in /Users, then created a new user from the Users & Groups menu with the
same name.
The name change was successful and I've retained my documents and apps but
for some reason my computer doesn't think rails is installed.
Do I have to add something back to a path variable?
Edit: Brew Doctor revealed that it seems to be an ownership issue and told
me to chown several directories in usr/local/
Are there any other important directories I should change the ownership
on? I thought creating the new user would have done this for me.
Thanks
