bigdecimal - Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

[col-panic]

Using redmine:5.1 and adding the plugin https://github.com/kontron/redmine_oauth to
the plugins directory, the errors added at the bottom are shown on startup.

After some research I found that some development tools are missing for inclusion of this library.
Unfortunately I could not find information on how to proper modify the image to allow for
inclusion of such plugins.

Any hel appreciated!

redmine-1  | You should probably keep only one of them.
redmine-1  | Remove any duplicate entries and specify the gem only once.
redmine-1  | While it's not a problem now, it could cause errors if you change the version of one of them later.
redmine-1  | Bundler can't satisfy your Gemfile's dependencies.
redmine-1  | Install missing gems with `bundle install`.
redmine-1  | Your Gemfile lists the gem puma (>= 0) more than once.

The following Dockerfile works (info from https://stackoverflow.com/a/63019924/905817):

FROM redmine:5.1

RUN set -eux; \
	\
	savedAptMark="$(apt-mark showmanual)"; \
	apt-get update; \
	apt-get install -y --no-install-recommends \
		build-essential \
	; \
	rm -rf /var/lib/apt/lists/*;

bigdecimal library gets built and starts up. So only the package build-essential is missing.
Would it make sense to include this dependency by default? It could be part of the initial image,
but effectively be removed (purged) after successful startup!
