install rmagick ubuntu

caffo () — Thu, 14 Jun 2007 02:44:18 GMT

let's undo some of the damage (just in case):



sudo apt-get remove --purge librmagick-ruby-doc librmagick-ruby1.8

Next let's get the version we need:



sudo apt-get install libmagick9-dev ruby1.8-dev

Lastly, go grab rmagick, the gem



sudo gem install rmagick
