     Could not create Makefile due to some reason, probably lack of 
     necessary libraries and/or headers. Check the mkmf.log file for more 
     details. You may need configuration options. 

     Provided configuration options: 
     --with-opt-dir 
     --with-opt-include 
     --without-opt-include=${opt-dir}/include 
     --with-opt-lib 
     --without-opt-lib=${opt-dir}/lib 
     --with-make-prog 
     --without-make-prog 
     --srcdir=. 
     --curdir 
     --ruby=/usr/local/bin/ruby 


     Gem files will remain installed in       
/var/www/html/snorby/vendor/bundle/ruby/1.9.1/gems/rmagick-2.13.1 for inspection.

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. `
