Their is a patch to fix this, seems the new release broke the boulder
roll code, so the hidden mechinism is broken.

You can at this time either use the Gate pass, which will/should
automatically open the gate on approach, or use the Password.

That password will probably disappear in the next release with the guard
giving some guff about `` Miss-use by non-citizens '' or some such. The
Gate and Port Passes are to be the normal means of ingress and egress
for scorn, with a alturnative (and difficult) smugglers route via the
old `under city'.

Hey those viking smuggers in the port well mean business!

I include the patch below.

Subject: CF: A patch for the boulders & gates bug
Date: Wed, 03 Feb 1999 21:49:39 +0900
From: Nishita Seikoh <s-nisita@ics.es.osaka-u.ac.jp>

Hello.

Recently, boulder & gate bug is reported at this mailing list.
Today, I hacked the source code.
(I refer the comment in server/time.c)

/* Check to make sure that only non pickable objects are above the
 * gate.  If so, we finish closing the gate, otherwise, we fall
 * through to the code below which should lower the gate slightly.
 */

The problem is that objects which can roll is not concidered. 
So, I made a temporary patch.
I hope the following patch will work fine.

Thanks,
S.Nishita.
