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/qt3-mac
%  sudo port install qt3-mac  
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 qt3-mac
--->  Verifying checksum for qt3-mac
--->  Extracting qt3-mac
--->  Configuring qt3-mac
--->  Building qt3-mac with target all

--->  Staging qt3-mac into destroot

--->  Installing qt3-mac

- 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 qt3-mac with these commands:

%  man qt3-mac
%  apropos qt3-mac
%  which qt3-mac
%  locate qt3-mac
