I'm getting this version of this error, and neither of the suggestions above helped, sadly:

Incorrect MySQL client library version! This gem was compiled for 5.5.27 but the client library is 5.6.22.

There is an error in this gist.

Here, use "--with-mysql-config" instead of "–with-mysql-config" (note two short dashes instead of a long one).

If this fails to update a mysql2 then one could just use an another RVM ruby version or a new separate RVM gemset.
