My google searching discovers this is pervasive. None the less, I can't
seem to solve it on my system.

If I type: sudo wireshark in Terminal (and give password) then I get:
Don't use sudo for running wireshark.
use it to change the permissions of /dev/bpf* son that your user can
read from them.

Assuming your user belongs to group  admin(80) you should:

$ sudo chgrp admin /dev/bpf*
$ sudo chmod g+r /dev/bpf*

And then run wireshark as you, not as root (you do not want the files
that wireshark creates being owned by root).

(wireshark:528): Gtk-WARNING **: cannot open display:

If I navigate waaaaay down the tree in
opt/local/var/db/dports/software/wireshark/0.99.5_0+darwin_8/opt/local/share

and double click the unix executable Wireshark, then it runs but
obviously hasn't the ability to find the network points.

One time, shortly after re-installing X-11 this morning, I was able to
do a sudo wireshark and have it run corectly AND locate the various
network points.

When I discovered that none of my running programs could get to the
Internet anymore, I suspected Wireshark had intercepted the en1 path and
thus I re-booted ... all worked fine except I no longer can run wireshark.

Would some kind soul guide me back to success?

thanks ...
