installcheck-world failure

I just started trying out the new make targets with "world" in the name.`make world` and `make install-world` seem to
work(unless I'm missing
 
something), but `make installcheck-world` ends with "Error 2".  The
relevant bits seem to be:

The differences that caused some tests to fail can be viewed in the
file
"/home/kgrittn/git/postgresql/kgrittn/contrib/dblink/regression.diffs". 
A copy of the test summary that you see
above is saved in the file
"/home/kgrittn/git/postgresql/kgrittn/contrib/dblink/regression.out".
