Let me preface this by saying that I don't think I totally understand
what you are trying to do here.

Not sure, but maybe this will help:

This shouldn't be a problem at all.  Don't forget that as a package
maintainer, Adrian, you only need to worry about $AUTHOR_VERSION, not
$VERSION. 
  APA> Package build process controls date of package release.
What's wrong with this?

Just the version number.  'date' and 'build-date' (see doc string in
above function) are both generated.
  APA> This can't work.
Sure it can.
  APA> What can we do?
Well, possibly (hopefully) I've given you the tools to answer that.
