If you need to install wget on OS X 10.6 you can follow these steps to install the latest and greatest version of it. If you dont want to compile from source you can always use Darwin Ports, or Fink. The following steps are performed from the Terminal.app once you have the file downloaded.
- Download the wget source
- tar -xvzf wget-latest.tar.gz
- cd wget-latest
- sudo make install
- wget should now be in /usr/local/bin
