--- Comment #16 from David Naylor <d...@freebsd.org> ---
I would like to add my 2c on PYTHON_VERSION:
There are, I think, two situations where PYTHON_VERSION adds functionality that
FLAVORS does not provide:
- if a port supports multiple versions of python but does not support FLAVORS
(for example end user programs[1]).
- if a port supports multiple versions of python but is only a consumer of
python (be it for building or for support scripts at runtime)
In both these cases if someone wants to use a different version of python,
without changing the default version of python, then PYTHON_VERSION is the
recommended (and currently supported) way.
I do, however, think FLAVORS and PYTHON_VERSION need to be enhanced,
specifically:
- setting PYTHON_VERSION then forces the default FLAVOR, and
- setting PYTHON_VERSION outside the range of FLAVORS gets that version added
to FLAVORS
Alternatively, we need to drop support for using using non-default versions of
python (and correctly handle when a port does not support a default version).
