[Mac os 10.9.5] "Symbol not found: _fchmodat"

[Hixie]

Mac OS 10.9.5, factorio 0.11.8

On first launch, if it tries to update the scenario pack, it crashes with:

Dyld Error Message:
Symbol not found: _fchmodat
Referenced from: /Applications/factorio.app/Contents/MacOS/factorio
Expected in: /usr/lib/libSystem.B.dylib

If I relaunch, it doesn't crash the second time, it says: "update failed: File /Applications/factorio.app/Contents/data/scenario-pack/changelog.txt has unexpected content". But the update appears to actually work fine? It appears in the mod list, anyway, and the directory has lots of files in it.

Here's the stack trace for the crashed thread (3):

Hi, thanks for the report. It seems to be a bug in boost. We have patched it locally, and the problem should hopefully be gone in 0.11.9.
