This isn't an error, but I wonder whether using a libtool built
elsewhere (Tiger's default version, or perhaps one from a more
successful build) would help isolate the problem.

I don't think so -- this warning pops up frequently, and I haven't
seen it associated with problems before.

I'm more than a little surprised to see a link against a static libc,
let alone two versions of one. This is why I'm picking on libtool
above; while I don't see anything in the link command that specifies a
static link, I wonder whether libtool is tweaking the environment in
order to specify this. I wish I could be more specific, but I don't
have any machines running Tiger yet, so I can only speculate.

That's a polite way to put it. My guess is that libtool.m4 or TIger's
implementation of gcc4 has a bug.
