This is unfortunately not really helpful. We don't see what are the 
differences, only that there are differences. A diff would be much better.

$ diff -u aggregator-module.po aggregator-module-new.po

It could very well be that the drupal-pot templates are for an 
older/newer Drupal version, then what you run your extractor on. The 
last update to drupal-pot was for the 5.1 release, so running potx on 
the 5.1 release code could result in comparable templates. I'd suggest 
you do this if you would like to see whether there are real differences.
