make: *** [infrakit] Error 1

Is this result repeatable for you? This appears to be a build toolchain issue, i'm also wondering if it recurs on go 1.7.

[annismckenzie]

Go 1.6.2 simply does not work correctly on Sierra – see the note here: https://golang.org/doc/go1.7#ports. If you upgraded to Sierra, you need to upgrade to Go 1.7.1 and you also need to delete your old binaries in $GOPATH/bin. There's multiple problems with Go binaries built on pre-Sierra systems; inconsistent mutex states, segfaults, and others. Unfortunately, nothing the op can do here.

Hi guys - like I mentioned, the Go 1.7.1 binaries fixed everything. Happy to close the issue - but it may be worth updating the docs.

[wfarner]

Thanks, folks! I've added a doc line to warn others, feel free to comment on the PR if you'd like to massage the wording.
