This is because in git the "id" of a changeset is its sha1 checksum. Given that, you can only reference it in a subsequent changeset. This is a problem in that there is no git built-in way to correlate a built binary with a particular changeset id of its sources but you end up using your own convention. E.g. set env. var VERSION or some such to the id during the compile step but it is a bother.
