- The standard search path for Ruby libraries, `$:`, has changed in accordance with [:Packaging/Ruby:the packaging guidelines]. Changes were also made to some of the entries in `Config::CONFIG` in the `rbconfig` module. The most important changes include:
- 
-  * `sitedir` and related directories (`sitelibdir`, `sitearchdir`) are now under `rubylibdir`.  Instead of `/usr/lib/site_ruby` they are underneath `/usr/lib/ruby/site_ruby`.
-  * The directories for architecture-independent pure Ruby code are always under `/usr/lib`, even on x86_64 architecture, where they used to be under `/usr/lib64`.  This change affects the `Config::CONFIG` entries `rubylibdir` and `sitelibdir`.
- 
- Directories that were previously in `$:` remain there for the time being, so that existing code, such as `/usr/lib/site_ruby`, does not need to be modified. These directories are deprecated though, and will be removed by the release of Fedora * 8.  Build Ruby RPM packages in accordance with [:Packaging/Ruby:the packaging guidelines]. In particular, Ruby libraries should only be installed into `sitelibdir` and `sitearchdir`.  You should also follow this rule for Ruby code that is not packaged as an RPM.
