ruby's rmagick.so error

Arch is cool but you should never panic! )

After Arch’s rmagick library update I got my ruby bindings broken!

$ script/console
...
Exiting
/usr/lib/ruby/gems/1.8/gems/rmagick-1.15.14/lib/RMagick.so: This version of RMagick was created to run with ImageMagick 6.5.4 (RuntimeError)
but ImageMagick 6.5.6-1 is installed on this system. You should either
   1) Configure and build RMagick for ImageMagick 6.5.6-1, or
   2) download ImageMagick 6.5.4 from file:///usr/share/doc/ImageMagick-6.5.4/index.html and install it.

So lets try to reinstall

$ sudo gem install rmagick -v '1.15.14'
