Yep, 1.9.0, snow leopard (10.6.3), and x86_64 here.  Sorry, I guess I
didn't mean registry, it just looks in the index.  Ok, so this sort of
thing will occur whenever there is a dependency that only occurs in
certain situations, such as this one where you only need yasm if
various parameters are met.  Or perhaps more specifically, whenever
your "situation" differs from the one used to generate the index for
your platform.  I think this can only happen for build-deps, right?
So this is not particularly problematic.

I wonder why this just popped up now though.  When I started this
thread a week ago yasm wasn't found like this by port_cutleaves and
nothing relevant in the x264 portfile seems to have changed in a long
time.  But I guess it's possible that previously some other port
depended on yasm and that dependency was removed in the past week.
