This file compiled when it was in core/platform/ but fails once I move it to
platform/ . Experience tells me this is a .gyp problem (possibly including a Mac
system framework), but I don't know how to solve it. Nothing in core.gyp or
blink_platform.gyp jumps out at me. Help?

Bump. Can someone help with this?

The try bot had no logs for the build failure.  Let's try sending this through
the CQ again.
