One of the suggested alternatives (that looks more viable to me now because
of incompatibilities between libedit and libreadline) is to have
libreadline as INTERNALLIB. So that it is not exposed outside of gdb build.
So that if we ever decide to replace gdb with something else in the base
all we have to do is to svn rm gdb and friends.

In other words, I suggest to reduce the number of dependencies on base
system libreadline to just base system gdb.

E.g. we do not expose expat from our base system to the outside world
because we do not want to have unnecessary dependencies between base and
ports.

Show me a non-GPL consumer of libreadline in /usr/src and I'll do

Your sentiment was about having libreadline port/package to be installed on
almost every system. We already have such packages (libintl and libglib2)
so there is nothing wrong with having libreadline as a port/package and it
does not imply that we should have it installed with the base system.
