Unable to install specific gem

I have an exsisting Ruby On Rails project that I am trying to get up and running, but when I try to migrate the db it says:

$ rake db:migrate 

Could not find json-1.6.5 in any of the sources

When I then try to install the specfic gem, it fails!

$ gem install json -v '1.6.5'

Fetching: json-1.6.5.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

        /Users/dev/.rvm/rubies/ruby-1.9.2-p136/bin/ruby extconf.rb

sh: make: command not found


Gem files will remain installed in /Users/dev/.rvm/gems/ruby-1.9.2-p136@rails3/gems/json-1.6.5 for inspection.

It looks like you are missing some command line tools.

verify that you have make installed

$ whereis make

should return something like:

/usr/bin/make

and

$ make -v

should be similar to:

I think you need to install the system dependent package libjson-ruby for ruby. Installing this package will solve this error.
