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 doesn’t work.

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
