The popular name for GNU ls is actually `ls', given that you install
Coreutils from the release tarball.  Favoring `gls' over `ls' will lead
to Emacs overlooking a potentially newer Coreutils installation as long
as one from the package manager is already present.

Have the BSDs abjured the nasty habit of placing site software in a
single /usr/local directory?  If so, we could perhaps search in the
directory where they install GNU software, i.e. /usr/sfw (?)
