After having updated gettext, I'm finding a number of ports that are linking against libintl (provided by gettext) but don't declare a dependency on gettext.

The question I have is, would some of these ports have worked if gettext wasn't installed, but just happen to link against libintl for extra functionality if it's there? I don't want to go adding gettext dependencies all over the place if it's not strictly needed, but on the other hand I'd like to be able to look up all ports that link against gettext, since upgrading it changed the major version number (actually, only version number) of the library and so everything has to re-link.
