ruby-build for Debian ===================== While ruby-build is a great tool to build Ruby versions that are not available via APT, you should still use the Debian-packaged versions of Ruby whenever possible since they are tested and supported by the Debian community. Please do not report bugs you encounter while using your homebuilt Rubies to the Debian team; Rubies built by yourself are not supported. That being said, the package dependencies/recommendations for ruby-build should be sufficient to get you going building regular releases of MRI and REE and most popular gems. However, if you want to build prerelease Rubies/gems, JRuby or Rubinius, you will have to manually install the packages listed below. prerelease Rubies/gems ---------------------- If you want to build prerelease Rubies or gems, you might want to install ruby-build with "--install-suggests" or install the following packages manually: - autoconf - automake - bison - git-core - libtool JRuby ----- If you're a JRuby user, you should install a package that provides a Java runtime environment. Typically, default-jre provides what you need. Rubinius -------- If you would like to use Rubinius, you should install these packages: - bison - rake - ruby-dev
