           Summary: games/nethack34-nox11: Cannot run the game as non-root

Running nethack-nox11 (installed via pkg) as any user, except for root, makes
the game exit with the error:
    "No write permission to lock perm!"

THE CAUSE OF THE PROBLEM:
-------------------------

The game is trying to create a lockfile (named "alock.$NUM") in
"/usr/local/share/nethack/".

That directory, however, is owned by root:wheel, and not root:games;
furthermore, it is not writable by group.

POSSIBLE SOLUTION:
------------------

I believe the best solution is to have nethack write the lockfile in
"/var/games/" instead (which has the correct group and permissions) --- that
directory is currently unused. I suspect it was intended for that purpose in
the first place.

---

In case anyone else has this problem: a temporary solution is to do the
following:

    chgrp games /usr/local/share/nethack
    chmod g+w /usr/local/share/nethack

This will ensure the game can create lockfiles in said directory. The user does
*NOT* need to be added to the `games` group (/usr/local/share/nethack/nethack
has the setgid bit set).
