Comment (by kencu):

 Here's what I did to build ld64-127 on Tiger (PPC). First copied over the
 MacOS10.5.sdk from a Leopard system, and then did these changes to the
 ld64 Portfile:

 there is a slight issue that I haven't sorted out completely with the
 {{{crt0.o}}} files --- the one in the 10.5 SDK is different than the one
 in the 10.4 SDK. I forget just now which way I got around that -- I think
 I copied the 10.4 one into the 10.5 SDK to build this -- I'm sorry, it was
 a couple of months ago now and I don't fully recall.
