Our current mac builds are failing during packaging, both SeaMonkey and TB.
From inspection of the affected range, it looks like it was the m-i merge at http://hg.mozilla.org/mozilla-central/pushloghtml?changeset=dcf6e5163e63
Of which the most likely culprit seems to be gavin's Bug 696436 ( http://hg.mozilla.org/mozilla-central/rev/6b18f5259de9)
I'm working on a patch but unable to test easily, try might work though.

Attempt 1, untested so far.

Diffs from my review, which I'll land with the patch.
I think this will get everything working again including suite, though I haven't explicitly tested that as I was running out of battery.

Assuming this passes build on trunk for Thunderbird and SeaMonkey, then you have a=me for transplanting the changeset I landed to Aurora.
