When I run bundle exec rspec spec/ I get the following messages in the console:
Could not open library 'libgtkmm-2.4': libgtkmm-2.4: cannot open shared object file: No such file or directory.

But, all of the tests pass and my app works just fine. Can anyone fill me in on what may have happened? Should I just scrap this box and clone my repo into a fresh one? I'm using Ruby 2.0.0p247 and Rails 4.0.2 in a Nitrous.io box. Thanks.
Even though unrelated (thank google for finding this), I have been trying to install Nitrogen for Ubuntu today. I get the same error. Seems like a specific GTK library has gone missing recently from either your system or your distro's repository (if you're even using Linux).
If you're using a Linux system, install the libgtkmm packages and if you're lucky enough, your missing library will be in one of those.
Use in Ubuntu this to install all of them:
sudo apt-get install libgtkmm*
Hope this helps.
