Go build for 1.6.x with OS OSX fails (Migrated from GitHub)

Our builds for Go 1.6.x on the OSX os fails with the error:

$ GIMME_OUTPUT="$(gimme 1.6.x | tee -a ${TRAVIS_HOME}/.bashrc)" && eval "$GIMME_OUTPUT"
/Users/travis/bin/gimme: line 357:  1883 Segmentation fault: 11  GOROOT="${1}" "${1}/bin/go" version >&/dev/null
I don't have any idea what to do with '1.6.4'.
  (using download type 'auto')

It looks like travis is unable to get Go 1.6.3 or Go 1.5 for the OSX os.
