This strategy is only used in one formula, so we can just replace it with a dependency. It could be done with a requirement, but since this is a low-impact change (it only matters for head builds on Leopard), I'm not sure it's worth the effort. The constant is retained for compatibility, though I could find only one other reference to it on GitHub, in a formula that was removed from core almost two years ago.
