Table Visualizer under OS X

[Rudolph van Graan]

Hi Vance,

I've compiled Erlang using the darwinports based process on Panther and  
so far everything (specifically table visualizer) works as advertised.  
It has been a (small) schlep to get darwinports running at first, but  
after the cvs checkout, it went smoothly. Erlang also compiled  
properly.

This is my list of installed ports:

wyemac:~ root# port installed
The following ports are installed:
         apr-0.9.5
         apr-util-0.9.5
         db4-4.2.52
         erlang-R9C-0
         expat-1.95.7
         gawk-3.1.3
         joe-2.9.8-pre1
         neon-0.24.4
         openssl-0.9.7c
         subversion-0.37.0
         tk-8.4.5
         xemacs-21.5.16
