[newbie] security, permissions, and NetHack. . .

[Norvell]

I recently switched from RedHat 6.1 to Mandrake 7.0 and tried installing
NetHack.  Before, I had to copy the files out of the tarball via
Midnight Commander (or else the permissions wouldn't work right),
instead of just doing a `tar xzvf nh330lin.tgz' while in the /
directory, as the README instructs.

Apparently Mandrake's security works differently than RedHat's.  When I
follow the same procedure for installing NetHack under Mandrake, I get
the following error when I try to play the game (and I'm logged in as a
user who is a member of the games group):

        NetHack, Copyright 1985-1999

        perm_lock: Operation not permitted
        Cannot lock perm for unknown reason (1).

Thanks for any help with this.
