No nightly HEAD builds in directory module?

I'm sure that this is due to my mis-use of CVS - I've checked in a few changes recently, and yet - no builds from HEAD branch. Basically nothing since the new release system was put in place.

http://drupal.org/node/90450/release

According to that page, the last HEAD build was Nov. 13 2006. I've checked in several changes since then. I've tried tagging with the new tagging convention (and it's possible that I've not done that right.)

So, what's the best way for me to diagnose this? Is this due to mis-tagging or other pilot error on my part?

Thanks!
