Create your own extensions. This may take some time ... ERROR: error installing json: ERROR: Failed to create native gem extension.

    /Users/..../.rvm/rubies/ruby-1.9.2-p180/bin/ruby extconf.rb

makefile creation

makeup sh: make: command not found

Gem files will remain installed in /Users/danieljreardon/.rvm/gems/ruby-1.9.2-p180/gems/json-1.6.3 for verification. Results recorded in /Users/danieljreardon/.rvm/gems/ruby-1.9.2-p180/gems/json-1.6.3/ext/json/ext/parser/gem_make.out

I am very new to development, so any simple instructions and tips would be highly appreciated. Thank you in advance!
