Sorry, I forgot to mention I'm running on an Intel machine (MacBook Pro), and running the Intel packages.

When targeting OS X v10.5, the linker creates images that contain both the new and traditional LINKEDIT segment format; this practice allows programs to run on OS X v10.5 and run very efficiently on OS X v10.6. (When targeting OS X v10.4 or earlier, the linker produces only the traditional format.)

Maybe "[creating] images that contain both the new and traditional LINKEDIT segment format", at least with that version of the linker, is not being done correctly; I'd assume that it puts in a load command for the "traditional LINKEDIT segment format" and a LD_DYLD_INFO, *without* LC_REQ_DYLD, so that the 10.5 dynamic linker silently ignores LD_DYLD_INFO and the 10.6 and later dynamic linkers use it.

That would be appropriate if building on 10.5 and targeting 10.6; I wouldn't *expect* that to be the default, but maybe software on the 10.5 buildbot was updated in a way that made targeting 10.6 the default.
