Thanks! You are correct, it appears that it only worked on my machine because I already had the dependencies. After investigating all morning, the only solution I can come up with is for you to run these commands first:
sudo apt-add-repository ppa:bartbes/love-stable
sudo apt-get install love
I'm open to suggestions about alternative approaches, but for now I might change the .deb so that it depends on love and will not allow the install until love is installed using the method above. Can you try it and let me know if that works?
