For gems with executables ruby installs a wrapper file into the executable directory by default. This can be overridden with the --no-wrappers option. The wrapper allows you to choose among alternate gem versions using _version_. For example `rake _0.7.3_ --version` will run rake version 0.7.3 if a newer version is also installed. If an extension fails to compile during gem installation the gem specification is not written out, but the gem remains unpacked in the repository. You may need to specify the path to the library's headers and libraries to continue. You can do this by adding a -- between RubyGems' options and the extension's build options: $ gem install some_extension_gem [build fails] Gem files will remain installed in \\ /path/to/gems/some_extension_gem-1.0 for inspection. Results logged to /path/to/gems/some_extension_gem-1.0/gem_make.out $ gem install some_extension_gem -- --with-extension-lib=/path/to/lib [build succeeds] $ gem list some_extension_gem *** LOCAL GEMS *** some_extension_gem (1.0) $ If you correct the compilation errors by editing the gem files you will need to write the specification by hand. For example: $ gem install some_extension_gem [build fails] Gem files will remain installed in \\ /path/to/gems/some_extension_gem-1.0 for inspection.
