Its been explained to me like this:

* libmysqlclient is GPL, with an exception given to things that are not
  GPL to link to it:

http://www.mysql.com/about/legal/licensing/foss-exception/

* OpenSSL is given an exception, despite being GPL incompatible

* However, now anything that links to *libmysqlclient* must also
  explicitly give OpenSSL an exception since they are effectively
  transitively accepting the OpenSSL license, which is not compatible.

With almost 150 reverse depends on libmysqlclient, it would be a lot of
work to make sure all of those projects gave OpenSSL an exception.
