This recent change to readline/libedit selection isn't quite right.
http://archives.postgresql.org/pgsql-committers/2004-11/msg00330.php
It doesn't link in libtermcap with libedit which leads to:
checking for readline.h... no
configure: error: readline header not found
If you have libedit already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper
directory.
Use --without-readline to disable libedit support.
And in config.log:
configure:5987: gcc -o conftest -O2 -Wall -Wmissing-prototypes
-Wpointer-arith -fno-strict-aliasing conftest.c -ledit -lcrypt -lresolv
-lcompat -lm -lutil >&5

This is on x86 NetBSD 1.6.
