They recommend not building from HEAD since it *might* be unstable.
And bazel in the AUR is 0.1.0 which is the version they test against,
and the version your PKGBUILD creates.
If it wasn't in the AUR already I would recommend you create a package
for it separately. :p Apparently it can be useful...

./configure should be part of build()
prepare() is for things like:
replacing "python" with "python2",
initing git submodules, and configuring them to fetch from a source=()
Anyway, I know linux-ck allows you to set an option to run `make
nconfig` during prepare() -- same deal with the linux package in core,
except there it needs to be uncommented.
makepkg won't break when requiring user input. But that ideally should
be limited to situations where there are valid choices that need to be
made -- it looks like you can simply export the right answers via an

I don't think so. Either they want to build it and they'll live with it,
or they don't. I haven't seen warnings like that for other packages.
I guess it is assumed people will make sure they have enough CPU and RAM
if they want to compile large projects.

You should add protobuf to your source=() array, and fix line 36 to
refer to the "google/protobuf" submodule -- not the "protobuf" submodule.
And why are you using /tmp to create the pip package rather than using a
directory inside the build directory?
