Worked on improving build-system reliability for the libquo package within the spack/spack and spack/spack-packages repositories. Addressed two critical bugs by refactoring dependency management, removing version-specific requirements for build tools such as m4, autoconf, automake, and libtool, and eliminating an invalid configure-time flag. These changes, implemented in Python and leveraging expertise in build systems and package management, simplified the build process and enhanced reproducibility across environments. The updates reduced CI build failures and streamlined onboarding and troubleshooting, providing a clearer maintenance path for complex dependency configurations and contributing to more stable and maintainable build workflows.
