Josh, 

I understand this reasoning, and yes, probably not finding current might usually indicate some sort of a problem. However, I was wondering if I could have some influence on this, in the case I intentionally want to overwrite default behaviour. 

In the concrete case it is about the Globus (future) ports. 

The packages which are bundled into the Globus Toolkit go here:
	http://www.globus.org/ftppub/gt5/5.2/stable/packages/src/

Updates between the Toolkit release seem to go here:
	http://www.globus.org/ftppub/gt5/5.2/stable/updates/src/

So the idea would be to search matches in the updates directory. If there is no match this would mean there is (probably) no update.

So is there a way to implement this?

Alternatively, one could try to collect matches from both directories and evaluate these. But I think this is not possible.
