Bazel bash completion script takes hours to build on macOS via MacPorts

[missa-prime]

Description of the problem / feature request:

Essentially, it takes hours to build the Bazel bash completion script on macOS when attempting to install Bazel via MacPorts. Building Bazel itself from source takes only several minutes, but somehow the bash completion script takes hours. There seems to be a hang that ends up resolving itself if you wait long enough.

Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

1. Make sure JDK 8 or newer is installed
2. Ensure that /etc/gitconfig file exists and user.name and user.email fields are populated
3. Install MacPorts from here
4. sudo port install bazel at a terminal prompt to install bazel

What operating system are you running Bazel on?

macOS 10.12.6

What's the output of bazel info release?

ERROR: The 'info' command is only supported from within a workspace.

Since I don't have a workspace handy, I'll provide the output of bazel version:

Build label: 0.9.0- (@non-git)
Build target: bazel-out/darwin-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Fri Aug 1 19:08:22 +50104 (1518980756902)
Build timestamp: 1518980756902
Build timestamp as int: 1518980756902

If bazel info release returns "development version" or "(@non-git)", tell us how you built Bazel.

Bazel was built from source while being installed with MacPorts.

What's the output of git remote get-url origin ; git rev-parse master ; git rev-parse HEAD ?
