    as it seems, you’re missing a sane build environment for building native extensions. A short explanation: Besides the libraries written in ruby ( there are tons of them ), libraries with bindings to lower-level code written in c exist ( some XML Parsers, RMagick, MySQL.. ). They rely on their low-level counterparts to be installed, and they also need a c compiler to build their interfacing part.

    So if you do not have a c-compiler like gcc and the whole build environment ( including make, autoconf and the whole bla ) installed, you won’t be able to build those native extensions.

    Hope that was of some help 🙂
