Too simple to even discuss here- the MDC docs are clear enough that you don't need more from me. The only issue that came up was, using Fink on Leopard requires that you build it yourself at the momment. Fink's homepage has a good doc on how to do this and I didn't have any trouble installing it. However, the MDC build docs say that once fink is installed you call <code> sudo apt-get install orbit orbit-dev and glib </code> - I could not get the packages that way even though apt-get was installed and working and I was able to list the packages in fink. In the end I called <code>sudo fink install orbit orbit-dev glib</code> and that worked just fine, all systems go to do mozilla building on the new toy.
