Thank you for the report, libeditline should really not depend on Ncurses!

In fact, I run it daily on a system where Ncurses really would not fit! So the above configure check should most definitely be fixed! The code in question is actually guarded inside a big

#ifdef CONFIG_USE_TERMCAP

so I guess it all boils down to my weak autoconf-fu. Terribly sorry about this! :-/
