What happens if you run

ldd /usr/local/lib/libreadline.so ?

It looks like you've got either multiple versions of readline
installed and you're linking to the wrong one, or something is really wonky
with your readline build. A quick google is showing that all of those
symbols are in ncurses, which means that you should probably have ncurses in
your linker cache or linker runtime path.

By the way, if you don't want readline functionality in psql (or care),
just build '--without-readline'
