To replace 'wget', you can download it from one of the GNU software mirror sites (it's in the 'wget' directory) and compile it yourself (this will require the Developer Tools to be installed). Once you've downloaded and expanded the archive, simply "cd" to that directory and type "sudo make install" to install the new 'wget'.
Once I've received my Dev Tools CD, I'll make a pre-compiled version available on my mac.com home page.
