Build deps have never been recorded in the registry. The important thing
here is what's in the index. x264 only depends on yasm if you are on
Snow Leopard and building for x86_64, or if the asm variant is set. This
is the sort of situation that prompted the switch in 1.9 from a single
PortIndex generated on the server to one for each supported platform.
Are you running 1.9.0?
