Unable to get ImageMagick version *** extconf.rb failed ***

Question

i've googled this error a couple of times and got instructions to install rMagick win-32 from their website. However the win32 versions looks depecrated and is made for Ruby 1.8.6 as for i have 1.9.3.

Can someone please help me install this gem? I really can't be arsed to do the imageMagick installing on my PC for this since the code will be moved to other PC's etc. a couple of times in the next few weeks (school assignment, you know how i goes). And with that it appears that imageMagick CAN be installed along with this gem(Which is by far the best option in my case). Nonetheless, i can't figure out this error since i'm a pretty big n00b when it comes to these things.

    An error occured while installing rmagick (2.13.1), and Bundler cannot continue.

    Make sure that `gem install rmagick -v '2.13.1'` succeeds before bundling.

You need to install dev packages:

sudo apt-get install libmagick++-dev

Hope this helps :)
