The thing is when you start pulling the string on this then you have to handle
all the other cases, because ports binaries will end up with some rpath to make
sure it finds in priority things from localbase, but then if it is also linked
to libarchive, ncurses, etc it will grab the localbase version as well
(depending on the shlib version of those) so doing the job for one of the lib
means doing it for all others.

For now candidates are:
readline (which will have then to be linked to ports ncurses and not base
version through the magic of fake libtermcap)

for now I do have:

which will make switch from USE_OPENSSL to USES=ssl is for ncurses basically USES=ncurses will die and ncurses will just
become a regular LIB_DEPENDS

When it becomes fun is that now all ports will have to really respect LDFLAGS...

I already found a couple of bad boys in that area.

btw that should also solve some issues with python and its ncurses module.
