If the package *requires* IPv6 to build, it should not simply be deleted;
rather, some mechanism should enforce the IPv6 capability, and fail if the
user requested no use of IPv6. Otherwise you're left with ambiguity as to
whether the user's USE_INET6 (or more properly, "inet6" package option)
choice was respected.
(A sample of what I'm currently doing for these cases, pending a new options
feature from dillo, is in net/sipcalc. It uses the newer "inet6"
PKG_OPTIONS, and forces it to be present -- failing if it was turned off, or
if the platform does not support it.)
