closes #14363

cabal requires either curl or GNU wget to download dependencies
via http. curl seems to be slightly better supported hence depending
on that. Unfortunately, we can't express either package A or package B
without virtual packages in $depends.

Alternative: patch cabal to make its default options compatible with
BusyBox wget or just leave this up to the user though cabal simply
doesn't work without either curl or wget installed.

kea is supposed to replace dhcpd.

not used by anything- gcc has used isl instead for years

All aports that makedepends on postgresql-dev.
