memory of nobody

I have this 2009's Mac Mini .. and ever since been using MacPorts. Then a friend suggested HomeBrew . Seems pretty could, although I am not sure what difference it could bring since MacPorts already served the purpose (not entirely true, somehow you could have compilation breaks too). 10.5 uses Xcode 3.1.2. So I need to use 3.1.4. This could be done if I download the entire image (size around 900MB) and burn it to a DVD.   I need to register myself for an account with the status of Apple Developer and tick some checkboxes. Go here . When you successfully verified your email and click with authorization log in, you could see a search box. Insert Xcode and find 3.1.4.  And, I need to remove my MacPorts as well since it isn't suggested to have them co-exist. Tips to remove your MacPorts are here and here
