Take this for instance:
BUILD_DEPENDS=3D ${LOCALBASE}/share/${GUILE_VERSION}/...:
${PORTSDIR}/lang/guile
GUILE_VERSION!=3D ...
If guile is not installed (e.g. when pointyhat builds INDEX or prepares
a portbuild) then BUILD_DEPENDS is set to:
${LOCALBASE}/share//...:${PORTSDIR}/lang/guile
And that will cause things to fail. All commands must succeed and
produce the correct output regardless of whether or not guile is
installed.

While this solves the problem of keeping stderr clean, it will not
satisfy the requirements above.
