If indeed there is a mismatch in process version, no, there's nothing you can do. But that shouldn’t be an issue since you are using the latest version of LR to build the DNG. Where you'd have issue is IF you then used an older version of ACR on that DNG. They are not in sync. So either render the data out from LR, save off a DNG but don't try to edit that DNG in an older version of ACR. Or upgrade to CS6 so ACR and LR are on parity.
