I have update my system to Ubuntu 15.04 and now Rmagick can\'t be installed...
It gives me the following error:
$ gem install rmagick -v \'2.13.2\' Build
I had the same problem and I fixed it up updating rmagick. What I did was:
sudo apt-get install libmagickwand-dev imagemagick bundle update rmagick
And now bundle works correctly.
