The package referenced in the message was compiled as a never-build package, but it requires another package to which interface changes have been made. The named package cannot be used without recompiling because it was linked with a different interface of the required package.  

The only solution to this error is to manually recompile the offending package. Be sure to specify the never-build switch, if it is still desired.

Delphi版本不一致，需要重新编译该引用的包，编译完后，重新引用该包的.dcp文件，即可Build成功。
