To install mysql bindings for ruby, use this command
#gem install mysql
You might get the following error:
“extconf.rb:1:in `require’: no such file to load — mkmf (LoadError)”
This probably means that you forgot to install the ruby1.8-dev package. Just do an apt-get install ruby1.8-dev to fix this.
Again after this you might this error:
“Could not create Makefile due to some reason [..] Check the mkmf.log file for more details. [..]”
You should do what the error message tells you: check the mkmf.log! Search for this file using find /usr/lib/ruby/gems/1.8/gems/ -name mkmf.log. Usually, this error message appears because you forgot to install the -dev package for the extension you were trying to install. So if you wanted to install the mysql gem, you probably forgot to install the libmysqlclient14-dev first. Do an apt-cache search | grep dev to find the appropriate packages.

(See full trace by running task with –trace)
The problem is that you need the Ruby MySQL wrappers. This isn’t really clear from the error message. Install it using:
# apt-get install libmysql-ruby
