Missing -lncurses in Slackware Linux

I've been trying to compile midish, and have been getting an error:

In looking at the configure script, I see that the -lncurses that was
present in version 1.0.6 has been removed from the CVS snapshot for Linux,
but not for OpenBSD.  I'm running Slackware 14.0, and it seems that
-lncurses is also required for Slackware, so the test in the configure
script will need to be changed.  Thanks.
