Package won't validate LKP is wrong Version and Connections at package level


Task Error: The version of LKP EXISTING RECORDS is not compatible with this version of the DataFlow.

and connections not found:

Task Error: The connection "{6EA46583-95C9-429C-80BB-39EADFE81239}" is not found. This error is thrown by Connections collection when the specific connection element is not found.

Task Error: Connection manager "{6EA46583-95C9-429C-80BB-39EADFE81239}" does not exist.

(The connections are stored at the Project Level in this project and shared between the Packages)

Do I need to download the code and compile on my machine to match the release levels?
