Ports with version numbers going backwards: math/py-mpz

[chkversion]

** The following ports have a version number that sorts before a previous one **

 For many package tools to work correctly, it is of utmost importance that
 version numbers of a port form a monotonic increasing sequence over time.
 Refer to the FreeBSD Porter's Handbook, 'Package Naming Conventions' for
 more information. Tools that won't work include pkg_version, portupgrade
 and portaudit. A common error is an accidental deletion of PORTEPOCH.

 Please fix any errors as soon as possible.
