I actually get the following error when running wireshark, i.e. after a few seconds of a capture:

Macintosh:~ greg$ wireshark --sync
The program 'wireshark' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadMatch (invalid parameter attributes)'.
  (Details: serial 50746 error_code 8 request_code 152 minor_code 4)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Macintosh:~ greg$

Any ideas/suggestions?

The installation console out (which succeeded I believe) is below:

Macintosh:~ greg$ sudo port install wireshark
