Redis and Grunt not working on Heroku

[kjorg50]

Hello, I am new to using node.js, but I wanted to try and deploy this application to Heroku. I've followed your instructions in the Readme and I have everything working locally, but both the redis-server and grunt watch commands do not work on my Heroku application. The web dyno with coffee index.coffee works fine, but here is what shows up in the logs when I try to start a redis worker:

2013-11-13T06:55:53.219721+00:00 heroku[redis-dev.1]: Starting process with command `redis-server`
2013-11-13T06:55:53.777822+00:00 app[redis-dev.1]: bash: redis-server: command not found
2013-11-13T06:55:54.830721+00:00 heroku[redis-dev.1]: Process exited with status 127
2013-11-13T06:55:54.843111+00:00 heroku[redis-dev.1]: State changed from starting to crashed

When I try to start a grunt worker dyno I get a similar message:

2013-11-13T07:24:03.612764+00:00 heroku[gruntdev.1]: Starting process with command `grunt watch`
2013-11-13T07:24:04.215564+00:00 app[gruntdev.1]: bash: grunt: command not found
2013-11-13T07:24:05.416066+00:00 heroku[gruntdev.1]: Process exited with status 127
2013-11-13T07:24:05.427289+00:00 heroku[gruntdev.1]: State changed from starting to crashed

Since I'm a beginner with node.js I'm probably just missing some configuration file, but do you have any insight into what my problem might be?
