# I (Jochen Küpper) got explicit permission to distribute molden as a
# MacPorts port, given that the source-code is always downloaded from
# the authors webpage and we add a banner asking users to register at
# the following web-page: http://www.cmbi.ru.nl/molden/form.html

# Feel free to update checksums whenever a stealth upgrade of molden is out...

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

--->  Staging molden into destroot

--->  Installing molden

- 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 molden with these commands:

%  man molden
%  apropos molden
%  which molden
%  locate molden
