Error in installing do_mysql on Mac OSX

I’m not a fan of macs, and to add to my depression, Mac OSX have problems in installing the gems mysql and do_mysql. I tried the workaround found here. It didn’t work on the machine I’m using. The error I’m experiencing now is:

Building native extensions. This could take a while…
ERROR: Error installing do_mysql:

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:

–without-opt-include=${opt-dir}/include

Gem files will remain installed in /usr/local/lib/ruby/gems/1.9.1/gems/do_mysql-0.10.0 for inspection.

I don’t know even know what these development tools the error message is talking about. I was able to install all the other gems I needed except for these two. I do hope I’ll come across with a solution for this. Specially when I’m not used to the development environment on Mac Computers.
