If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/mysql4
%  sudo port install mysql4  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching mysql4
--->  Verifying checksum for mysql4
--->  Extracting mysql4
--->  Configuring mysql4
--->  Building mysql4 with target all

--->  Staging mysql4 into destroot

--->  Installing mysql4

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using mysql4 with these commands:

%  man mysql4
%  apropos mysql4
%  which mysql4
%  locate mysql4
