Some configure scripts accept an argument like
"--with-readline=/usr/pkg". Try it. If the script doesn't accept that,
you can usually force the issue thusly:

	export LD_RUN_PATH='/usr/pkg/lib:/usr/X11R6/lib'
	export LDFLAGS='-L/usr/pkg/lib -Wl,-R/usr/X11R6/lib'
	export LIBS='-L/usr/pkg/lib'
	export CFLAGS='-I/usr/pkg/include'
	export CPPFLAGS='-I/usr/pkg/include'
	configure

or some variation thereof. ["csh" users use "setenv" instead of
"export".]

The redundancy is often necessary, because "configure" always
recognizes "LIBS" and "CPPFLAGS", but doesn't always pass them to the
GNU makefiles. The GNU makefiles, on the other hand, usually respect
LDFLAGS and CFLAGS.
