I get an "Could not find RubyGem heroku (Gem::LoadError)" when I try to execute any Heroku commands from terminal in my app directory. Have tried wiping and reinstalling Toolbelt, as well as any previously installed Heroku gems.
Using the full path works and--app name works (/usr/bin/heroku config--app myapp-stage). Using OS X 10.8.1.
echo $PATH

$ heroku

Thanks in advance for any help or advice.
