Just upgraded (i.e. not a new install) to Lion from Leopard and my previously well-working rmagick now doesn\'t work anymore and gives me this error:
Your Rack
On Mac OSX Lion (10.7) with imagemagick installaed through homebrew this one fixed my problem:
First of all remove the broken rmagick from your rvm installation path: ~/.rvm/gems/ruby-1.9.3-p194/gems/
Afterwards reinstall imagemagick through brew and then run bundle again:
brew uninstall imagemagick
brew install imagemagick
bundle
