Rails Installation Broke Briefly as Dependency Yanked Old Versions of Gems — A bit of a complicated story this! In brief, MimeMagic is a library for detecting the MIME type of files, but it contained a GPL licensed file for years despite the project being MIT licensed. To rectify the problem, the creator switched MimeMagic to GPL and yanked (removed) the old versions upon which Rails had a dependency - oops! The author then released a new version to fix the problem, but the licensing remains a standing issue given the effects the GPL can have on consuming projects.
