No hay mucho más en mi pregunta que eso. gem install mysql
no funciona y no he encontrado nada mediante Google.¿Cómo instalo el adaptador Rails MySQL?
Cuando intento gem install mysql2

qué sistema operativo se ejecuta? Parece que no ha instalado MySQL y/o las bibliotecas de desarrollo requeridas. –
Estoy en Linux. MySQL está instalado, pero las bibliotecas de desarrollo casi seguro que no. ¿Cómo sé cuáles son? –
Depende de qué distribución está utilizando (es decir, Ubuntu, Red Hat, SUSE)? –
