插件包中的 dylib @executable_path 路径问题

我正在开发一个插件包, say MyPlugIn.bundle 申请, say BigApp.app. 该捆绑包需要 dylib, say MyPlugIn.bundle/Contents/Resources/library.dylib。我已经重新定位了library.dylib的路径，就像我对一个简单的应用程序包所做的那样：

$ otool -L MyPlugIn.bundle/Contents/MacOS/MyPlugIn
MyPlugIn.bundle/Contents/MacOS/MyPlugIn:
 @executable_path/../Resources/library.dylib (compatibility version 0.0.0, current version 0.0.0)
 [...]

$ otool -L MyPlugIn.bundle/Contents/Resources/library.dylib
MyPlugIn.bundle/Contents/Resources/library.dylib:
 @executable_path/../Resources/library.dylib (compatibility version 0.0.0, current version 0.0.0)
 [...]

但 BigApp.app 无法加载此包，Mac OS X 的 Console.app 会记录以下内容：

19/01/10 15:42:59 BigApp[51516] Error loading /Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn:  dlopen(/Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn, 262): Library not loaded: @executable_path/../Resources/library.dylib
  Referenced from: /Library/Application Support/BigApp/Plug-Ins/MyPlugIn.bundle/Contents/MacOS/MyPlugIn
  Reason: image not found

看来@executable_path不是由 MyPlugIn.bundle 可执行路径替换，而是由BigApp.app 可执行路径.

Any 解决方法对此，没有绝对路径，因此它将继续工作Mac OS X 10.4（老虎）？谢谢。
