I don't think this is easily fixable.

Here's the problem:

editors/libreoffice sets DEPENDS_ARGS=3DPYTHON_VERSION=3Dpython3.4
It builds www/serf with make *argument* (to override, intended)
PYTHON_VERSION=3Dpython3.4.

This PYTHON_VERSION make override propagates all the way down the chain,
overriding
the USES=3Dpython:2 in devel/scons.  It tries to set PYTHON_VERSION=3Dpytho=
n2.7,
but the
make argument forces it back to python3.4.

DEPENDS_ARGS is an interesting, and very old, hack that only really works on
direct dependencies.  Once it gets into a 2nd-order dependency then it can
cause issues like in this bug.
