(svn r3230) -Feature: [OSX] OSX builds can now change where it searches for dynamic libs and can move libs into the bundle This is not a fix for the issues with static linking, more like a workaround. Static linking still got issues Apple recommends to use dynamic linking anyway, so I guess this doesn't matter much
