libvpx: universal build fails

[devernay (Frédéric Devernay)]

(seen with a ppc/i386 build on Leopard, I don't know if other universal builds fail the same way).

libvpx/Portfile uses muniversal, but the package uses a custom configure script which doesn't recognize the --host=... argument. Consequently, merger_host should be set to "" for all archs. Portfile should have

    foreach my_arch ${configure.universal_archs} {
        set merger_host(${my_arch}) ""

        set merger_configure_args(${my_arch}) --target=$my_targets(${my_arch})-${os.platform}${os.major}-gcc
    }

instead of

    foreach my_arch ${configure.universal_archs} {
        set merger_configure_args(${my_arch}) --target=$my_targets(${my_arch})-${os.platform}${os.major}-gcc
    }

Remember to use WikiFormatting.

The universal variant work fine on Snow Leopard; I would not have committed it if I had not gotten it to work.

Could you please attach a main.log of the failure you experience?
