I don't know what the cleanest approach would be, but I like the idea.
I can imagine a PortGroup, something in the spirit of:
PortGroup legacy 1.0
legacy.support darwin 10
# legacy.support {darwin < 11}
which would add a dependency and append the necessary flags for darwin10.
(The library could be built statically.)
