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

--->  Staging oracle-instantclient into destroot

--->  Installing oracle-instantclient

- 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 oracle-instantclient with these commands:

%  man oracle-instantclient
%  apropos oracle-instantclient
%  which oracle-instantclient
%  locate oracle-instantclient
