Subject: [PATCH] python-utils-r1.eclass: Loosen minimal Python versions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Loosen minimal Python versions to accept any version in a given slot.
Lower bounds are cumbersome to maintain and cause problems when
upgrading outdated systems, particularly when sys-libs/glibc
is involved.

We could technically apply some hack to make any-r1 dependency checks
to conditionally ignore minimal versions but that sounds like
unnecessary complexity.  In the end, minimum versions were primarily
enforced to make sure users got the latest bugfixes but that doesn't
seem strictly necessary.
