   3 Subject: [PATCH] Rubygems: don't install platform-specific gems
   4
   5 Gems with native extensions typically contain just source code that is
   6 built during installation on user's system. However, Rubygems allows to
   7 publish even platform-specific gems with prebuilt binaries for specific
   8 platform. The problem is that Rubygems uses only short platform
   9 identification like x86_64-linux; it does not identify used libc.
  10 And sadly platform-specific gems for linux are built against glibc, so
  11 they may not work on musl libc.
  12
  13 This patch is a workaround for the aforesaid problem. It removes local
  14 platform from Rubygems' supported platforms to force it always pick
  15 a platform-agnostic (source) gem. Users can override it using
  16 `--platform` option.
