### FAQ

The standard library is installed in /usr/local/lib/ruby/1.9.1
: This version number is \"library compatibility version\". Ruby 1.9.2
  is mostly compatible with the 1.9.1, so its library is installed in
  the directory.

It causes a LoadError
: `$:` no longer includes the current directory. So some scripts need
  modification to work correctly. Anyway, your script should not depend
  on the current directory as well as possible.
