lang/php support for zip

[Rodolfo Gouveia]

I need support for zip in the lang/php/5.3.
Adding this on lang/php/Makefile.inc:
        .if ${FLAVOR:L:Mzip}
        CONFIGURE_ARGS+=        --enable-zip
        .endif
is the recommend way? pseudo-flavor or just flavor?
Any feedback is welcome.

cheers,
