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/hdf4
%  sudo port install hdf4  
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 hdf4
--->  Verifying checksum for hdf4
--->  Extracting hdf4
--->  Configuring hdf4
--->  Building hdf4 with target all

--->  Staging hdf4 into destroot

--->  Installing hdf4

- 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 hdf4 with these commands:

%  man hdf4
%  apropos hdf4
%  which hdf4
%  locate hdf4
