Readline on OpenBSD

How to get readline 8 on OpenBSD 7.3. (These notes are historical as I rewrote my midnoi(1) tool to instead use editline.)

    $ localarchdir
    OpenBSD7.3-amd64
    $ ./configure --prefix=~/usr/`localarchdir` && make && make install
    ...

This is something of a kluge, but the lib/pkgconfig/readline.pc file needs modifiction, notably to remove the termcap line, to add -lncurses, and to use rpath linking.

    prefix=/home/jmates/usr/OpenBSD7.3-amd64
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib
    includedir=${prefix}/include
