More (newbie) Macports issues

[Garrett Reid]

I have a fairly fresh macports install, but a few parts seem broken.
Any help would be much appreciated.

tcptraceroute doesn't work.
On a tcptraceroute google.com, I get:
libnet_write failed?  Attempted to write 40 bytes, only wrote -1

When I install ophcrack, it installs fine, but then won't run:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
(ophcrack:11749): Gtk-WARNING **: cannot open display:

I have installed (installed in this order):
wireshark
ettercap-ng
hping2
tcptraceroute
(deactivated libnet11, activated libnet for dsniff)
dsniff
ophcrack


Any ideas?
