We previously set `ignore_deps?` as true for DependencyInstaller to
avoid duplicated dependencies resolution. (See a9fc82aea30506eeacbddeb8b53fb85de8acb9d4)
However, this will cause problem when pouring bottle of a dependency is
failed. In this case, it will try to build dependency from source but
failed due to uninstalled build deps for this formula.
Another disadvantage for using `ignore_deps?` hack is we cannot
distinguish users passing `--ignore-dependencies` flag from we are in
`DependencyInstaller`.
So, let's differentiate these using `skip_deps_check?`
This is the (partially) documented public API for Homebrew. It's currently a work in progress. Sorry about that!
The main class you should look at is the {Formula} class (and classes linked from there). That's the class that's used to create Homebrew formulae (i.e. package descriptions). Assume anything else you stumble upon is private.
