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

--->  Staging scrypt into destroot

--->  Installing scrypt

- 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 scrypt with these commands:
