I\'ve got a problem

I\'ve finally managed to get MB to run under Debian GNU Linux, but now I\'m stuck under the island.
I managed to get out of the city, but after a while I fell into the ocean. /spawn doesn\'t work, so I guess I\'d have to update, just like the windows version. But my question is, is there any way for me to update to get /spawn to work or another way to get me back into the city?
I\'\'m using the CVS version, as described in acraig\'s guide.
