I wish it was so simple. The only way that portage is going to know about 
patches is when we tell portage about them. This would involve some file that 
describes how to get from source 1 to source 2. It also only would work when 
the ebuild doesn't explicitly unpack the source file. 

In short this is very complex and not really supported by portages original 
design. It would be nice though, but at the moment there are more important 
things to do for portage.
