Comment (by kencu):

 I think you might possibly be running into something we noticed a few
 months ago with the linker (ld64) on snow leopard. It is not happening on
 my machine, but this snowleopard machine I'm on is highly tuned, and
 highly compatible with newer software (see LibcxxOnOlderSystems if you're
 interested in that someday).

 The discussion about the linker issues was here [ticket:53931]. I thought
 we had that resolved.

 can you give me the output of `port -v installed | grep ld64` please. Here
 is what I have:
 {{{
 $ port -v installed | grep ld64

 }}}

 The current versions of libgcc build on the 10.6.8 buildbot in both i386
 and in x86_64 architectures. It builds universal on my machine. I'll wind
 up a VM at home I have and see if it will build +universal.

 It might not be a terrible idea to tweak the buildbot to build a
 +universal version for everyone as well, as it takes forever to build one.
