I am trying to install the gem mysql2 for Ruby Enterprise Edition . I am getting error that says: Installing mysql2 (0.2.7) with native extensions /Users/rookieRails/.rvm/rubies/ree-1.8.7-2011.03/lib/ruby/site_ruby/1.8/rubygems/installer.rb:551:in `build_extensions': ERROR: Failed to build gem native extension.

Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog Does anyone have any idea what configuration options I should use, or whatever I need to to to get this fixed?
