Summary (under 1500 chars):

- Exact error message and exit code
  - "Gem::Ext::BuildError: ERROR: Failed to build gem native extension."
  - "extconf.rb:40:in '<main>': The "libcurl" package isn't available. (RuntimeError)"
  - "An error occurred while installing ovirt-engine-sdk (4.6.1), and Bundler cannot continue."
  - "ERROR: process \"/bin/sh -c bundle install --without no_ci\" did not complete successfully: exit code: 5"

- Failing command/step
  - [6/6] RUN bundle install --without no_ci

- Missing packages or files mentioned
  - libcurl package isn't available
  - curl-config: not found
  - pkg-config for libcurl: not found

- Version mismatch info
  - Base image: ruby:3.4.9-alpine3.23
  - Gem: ovirt-engine-sdk (4.6.1)
  - The failure is due to missing libcurl development headers/tools, not a clear version mismatch; the extconf shows libcurl is required but not available in the build environment.

- Missing packages or files mentioned:

  - E: The repository 'http://deb.debian.org/debian buster Release' does not have a Release file.
  - E: The repository 'http://deb.debian.org/debian buster-updates Release' does not have a Release file.

- Version mismatch information:
  - The failure is due to Debian "buster" (Debian 10) repositories returning 404 for Release files, indicating end-of-life (Buster EOL). This suggests a mismatch between the base image (ruby:2.4.10) and the apt sources being used, where the Debian Buster repositories are no longer available.
