Systemic problem causing patch errors?

[Lars Eighner]

Yesterday I rebuilt and reinstalled 11.0-STABLE amd64. I then refreshed 
the ports tree with svnup ports and ran portupgrade -af. The result was 
that close to 50 ports fail to build because of patch errors, and of 
course several hundred dependent ports failed to build.

This would seem to me to indicate some kind of systemic error. How can I 
identify what I am doing wrong?
