Either way. I think it really depends on the package.
Your suggestion is optimal when features are mutually independent
(and in fact this is what i have done for SDL, SDL_IMAGE, SDL_TTF).
Version number/release dates are probably more appropriate for tools
with incremental features (so you can check VERSION >= XXX, e.g.
we do that in configure.ac) or for those where the feature set is
not well defined across versions (in which case you probably need
an exact match).
