We've heard of this happening as a result of libedit pulling in libbsd,
which provides (broken) versions of these symbols and thus confuses
configure into thinking they're present. The "-ledit" in your link line
suggests that you are linking to libedit, but the rest of that is just
guesswork. I'd suggest installing readline to see if the problem goes
away.

Here's a previous report:
