System: rn version 4.3
Patch #: 13
Priority: MEDIUM
Subject: Configure gets spoofed on terminfo vs. termlib.
From: lwall@sdcrdcf (Larry Wall)

Description:
	Several people have complained that Configure found what it
	thought was a terminfo system, only to find when rn was loaded
	that -lcurses didn't contain termlib routines.  Checking for the
	directories /usr/lib/terminfo or /etc/term is not really good
	enough.  The following patch makes Configure check -lcurses to see
	if it really has a termlib emulator in it.

	The patch also corrects a minor problem in that values in
	the config.sh file were surrounded by double rather than single
	quotes, which causes an unwanted variable substitution to occur
	on values containing '$', such as Log="$Log".  Rayan Zachariassen
	<rayan@utai.UUCP> pointed out the problem.

Fix:	From rn, say "| patch -d DIR", where DIR is your rn source directory.
	Outside of rn, say "cd DIR; patch <thisarticle".  If you don't have
	the patch program, apply the following by hand, or get patch.

	If patch indicates that patchlevel is the wrong version, you may need
	to apply one or more previous patches, or the patch may already
	have been applied.  See the patchlevel file to find out what has or
	has not been applied.  In any event, don't continue with the patch.
