从一台服务器移到另一台服务器时，遇到了redmine（或者rubyconfiguration）的麻烦
redmine@dirty:~/www$ ruby script/rails server webrick -e production /usr/local/rvm/gems/ruby-2.0.0-p353/gems/mysql2-0.3.14/lib/mysql2.rb:8:in `require': Incorrect MySQL client library version!

我已经重新安装了gem，捆绑，甚至包装，但仍然没有成功。

UPD2：
在旧的系统上，我使用ruby软件包，在新的Ubuntu的服务器11.10 – ruby由rvm提供
您正在使用本机扩展的gem，但它们是针对源系统上的目标系统上具有不同版本的库进行编译的。
所以你需要在目标系统上重build你的gem。
rvm use 2.0.0-p353 gem pristine --all
在将来，如果你只是部署你的源代码，并让bundler处理目标系统上的gem，而不是试图复制你的整个.rvm目录，那将会更好。
