crazy bug...

[moin]

I'm running osx leopard with sbcl from macports. If I disable the
network connection, sbcl loads. Otherwise I'm getting this console
error:


Sep 23 23:07:18 localhost [0x0-0x42042].org.eclipse.eclipse[384]: >>>

I would guess that when your network is on, your firewall does not
allow opening port 4005, which is used for communication between Cusp
and swank. Could you please check your firewall settings and report
here if that was the problem.

Thanks
