Comment:

 I don't think you can do that because then you can't upgrade it.

 I think you just have to in the unpackaged script run the check script
 version and return an error if it fails.  Since the package scripts are
 run in a transaction, I think the script will just bail out.

 In theory this should be pretty much a non-issue if done right, because
 since we add new functions on each minor, the unpackaged script for the
 current version would fail anyway because it would try to add a function
 not in current users install and then bail when it can't find it.
