10.5 Leopard and 64bit support

forgot to answer - thanks. That is what I was looking for. I removed PPC 
added 64bit intel and go!

Now I am delving in the typical issues where "bootstrapping" a wokging 
compiler set and dev tools on Leopard is not that easy, I asked Ken but 
will ask more on the list if I remain stuck

I have installed successfully clang 3.4 and sow nice 64bit processes in 
the meanwhile!

Now I am biting my teeth on glib2 which is a clang 3.9 dependency.
