Found this for future reference in case anybody else needs it

"Apple’s developer website <https://developer.apple.com/mac/> only links to
the latest version of Xcode, which requires Snow Leopard (Mac OS X 10.6).

If you’re still running Leopard (10.5), you need to go to this alternative
developer website:

http://connect.apple.com/
then look under developer tools in the right hand  column

Thanks guys.
