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 ran into same problem on clean Ubuntu 15.4 installation. Upgrade rmagick from 2.13.2 to 2.15.0 helped.
rmagick
2.13.2
2.15.0
Things I tried, that did not help:
/usr/include/wand
MagickWand.h
magick_wand.h
libmagickcore-dev
Hope it helps.
