Weird... I can use arrow keys just fine here in a Lucid build.  My emacs
executable lives in src/emacs and my PATH contains,

    ~/lib/ports/emacs/lib-src:~/lib/ports/emacs/src

where ~/lib/ports/emacs is where I have the Emacs repo cloned.

The way I launch Emacs doesn't seem to matter either: I tried
`./src/emacs -Q' and `emacs -Q' and both don't show the problem.  If it
is of any help, `xrdb -query' prints,

    *customization:	-color

[ To be clear, I have no Xresources file anywhere in my home directory.  ]
