This change automatically append MAJOR.MINOR Ruby version of the compiled extension in the target directory. A better picture: rake cross compile RUBY_CC_VERSION=1.8.6:1.9.1 Will generate the following files: lib/1.8/extension_name.so lib/1.9/extension_name.so 7f043d6e4d532d2035147c73fb4508c8720ddbe9 Luis Lavena luislavena@gmail.com
