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.
