Missing dbus headers when building on Amazon Linux 2

[Lee Nave]

First time trying to build Chromium, following these instructions:

https://chromium.googlesource.com/chromium/src/+/main/docs/linux/build_instructions.md

With this config:

> cat out/Headless/args.gn
import("//build/args/headless.gn")
is_debug = false
symbol_level = 0
blink_symbol_level = 0
is_component_build = false
enable_nacl = false

headless.gn sets use_dbus to false, however midway through the build I get:

Am I doing something wrong?

Thanks!

Trying again with the headless_shell target . . . 

[Lee Nave]

That worked.  Would be great to add a section about headless on the "Checking out and building" page that links to https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md.
