--- Comment #9 from Kubilay Kocak <koobs@FreeBSD.org> ---
(In reply to Sunpoet Po-Chuan Hsieh from comment #6)

This is the better option. The scons port should do nothing but declare the
versions *it* supports, and scons consumers ought to declare specifically t=
he
version(s) they support, allowing them to move forward at their own pace,
without 'imperative' selection by the framework.

Notes:

- It's worth considering having scons.mk support <version-specifier> in the
exact same way that USES=3Dpython supports it, rather than it being an FLAV=
OR
argument (scons:py27)

This allows, scons consuming ports to declaratively specify/declare version
support, rather than 'imperatively' 'choosing' a framework specific
implementation details (flavor)

This also enables / gives us the ability to factor out a generic
<version-specifier> support across more areas of the framework, starting wi=
th
Python / Scons, and improving it in the process ("!=3DX" support, "X,Y" sup=
port,
etc), which has huge benefits for consistency and version derivation across=
 our
tree.
