Lemonade is deprecated
Lemonade was a cool way to create sprites. Now I merged Lemonade into Compass in v0.11 and redefined the API with Chris Eppstein. Even better, Scott Davis made some enhancements.
So thanks for all the buzz for Lemonade and take a look at our Compass Sprites implementation:

Follow @hagenburger for updates.
Cheers,

Still need to use Lemonade?
Try to use an older implementation of ChunkyPNG if you get empty PNGs:
# Gemfile
gem 'lemonade'
gem 'chunky_png', '0.11.1'
You can find the old Lemonade code in the master branch
