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 vbs
--->  Verifying checksum for vbs
--->  Extracting vbs
--->  Configuring vbs
--->  Building vbs with target all

--->  Staging vbs into destroot

--->  Installing vbs

- 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 vbs with these commands:

%  man vbs
%  apropos vbs
%  which vbs
%  locate vbs
