Try "apt-get install libmysql++-dev" Since there was a lack of Operating system mentioned I'm going to assume it was a Deb based system. If it wasn't just do yum search mysql |grep dev. If this doesn't work please post the contents of /Users/Nabs/.gem/ruby/1.8/gems/mysql-2.7/gem_make.out so we can tell you exactly what's wrong.

You should try to do it as a root user:
$ sudo gem install mysql

Sudo does work on OSX. Try this for OSX:
gem install mysql -- --with-mysql-include=/opt/local/include/mysql5 --with-mysql-lib=/opt/local/lib/mysql5 --with-mysql-config=/opt/local/lib/mysql5/bin/mysql_config
