Полный текст решения: In order to reproduce the bug, dowload and unpack the attached tarball (simple.tar.gz). This contains three files: simple.c, helper.rb and the extconf.rb file. Run the extconf.rb script to create a Makefile for your operating system, then type "make" to build the extension.
Once you've built the extension, start up "irb" and then type: require "simple". You should get a warning message, "already initialized constant FOO". If you inspect the value of $", you will see that the shared library part (simple.bundle, or simple.so, depending on your operating system) has been loaded twice.
Помогите пжалуйста-))
