我使用在WWDC上獲得的光盤升級到了雪豹?，F在嘗試運行我的一些Rails應用程序會抱怨sql    (in /Users/coneybeare/Projects/Ambiance/ambiance-server)!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.Importing all sounds in /Users/coneybeare/Projects/Ambiance/ambiance-sounds/Import 32/Compressed/ -- AdirondackPeepers.caf!!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql.rake aborted!dlopen(/opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle, 9): Library not loaded: /usr/local/mysql/lib/libmysqlclient.16.dylib  Referenced from: /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle  Reason: image not found - /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/lib/mysql.bundle(See full trace by running task with --trace)我本可以發誓我曾經修復過這個問題。問題是sudo gem install mysql不起作用并給出錯誤： Building native extensions.  This could take a while...ERROR:  Error installing mysql:    ERROR: Failed to build gem native extension./opt/local/bin/ruby extconf.rb install mysqlchecking for mysql_query() in -lmysqlclient... nochecking for main() in -lm... yeschecking for mysql_query() in -lmysqlclient... nochecking for main() in -lz... yeschecking for mysql_query() in -lmysqlclient... nochecking for main() in -lsocket... nochecking for mysql_query() in -lmysqlclient... nochecking for main() in -lnsl... nochecking for mysql_query() in -lmysqlclient... noGem files will remain installed in /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7 for inspection.Results logged to /opt/local/lib/ruby/gems/1.8/gems/mysql-2.7/gem_make.out有沒有人得到mysql在雪豹上使用Rails呢？如果是這樣，您的設置是什么，更好的是，我該怎么做才能重現它？
