The config files go in /etc/uucp.

  It's unfortunate that the info documentation is not included with the netbsd
sources, since it's really essential to building a reasonably robust set of
config files (the included man pages do not discuss configuration).  It sounds
like you probably already have a configuration built elsewhere, but if not,
get a copy of the original source to Taylor uucp and install the info files.
Also, be sure to have an info reader (emacs or the standalone info program)
installed.
