Looking over some buildbot logs, I realized the following issue with the readline configure script: It always adds an extra -lreadline when checking for rl_completion_word_break_hook, despite the fact that sometimes we want to link with -framework GNUreadline. Thanks, -Judah * Don't test for rl_completion_word_break_hook with -lreadline if we're using GNUreadline.framework. M ./configure.ac -2 +2
