Buildout is very conservative about rebuilding things -- erring on the  
side of rebuilding.  IOW, if in doubt, builout will rebuild a part.   
When you upgrade buildout, it's possible that a change in buildout  
will affect how a part is built, so upgrading generally results on  
parts being rebuilt. There isn't currently a way to prevent this.
