Yes there is this consideration too.  Maybe we should have something
more elaborate then.  AFAIR, there is some test afterward to see if the
found "ls" support "--dired" so maybe if the found "ls" does not support
"--dired" and we are on a BSD then we should look for "gls".

I don't know what you are calling "site software" but yes (OpenBSD at
least) is using /usr/local for its package software.

There is no such directory by default on OpenBSD.
