Title: The latest sphinx formula fails if you don't have MySQL installed.

Installing sphinx via Homebrew fails when mysql isn't currently installed.

When installing the latest sphinx script, it defaults to mysql support unless --without-mysql is passed.

Changed to pass --without-mysql if the mysql binary isn't found, instead of passing --with-mysql if it is found.
