Dealing with gem dependency issues when installing Cinderella v0.3.5.

CinderellaDependencyFixes.md

Uninstall all messed up gems/dependencies

sudo gem uninstall net-ssh-gateway --all
sudo gem uninstall net-ssh-multi --all
sudo gem uninstall net-ssh --all
sudo gem uninstall moneta --all
sudo gem uninstall cinderella --all --executables

Install correct gem versions

sudo gem install net-ssh --version=2.1.4
sudo gem install net-ssh-gateway --version=1.1.0
sudo gem install net-ssh-multi --version=1.1
sudo gem install moneta --version=0.6.0
sudo gem install cinderella --version=0.3.5

Run cinderella

/usr/bin/cinderella

If Cinderella dies during ImageMagick installation, restart Terminal, then update Homebrew:

brew update

Then, rerun Cinderella. If it keeps dying, then try to manually install the component that's failing (using Homebrew).
