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:

make[2]: Entering directory
`/home/kgrittn/git/postgresql/kgrittn/contrib/dblink'
make -C ../../src/test/regress pg_regress

make[3]: Entering directory
`/home/kgrittn/git/postgresql/kgrittn/src/test/regress'
make[3]: `pg_regress' is up to date.

make[3]: Leaving directory

dblink

The differences that caused some tests to fail can be viewed in the
file

A copy of the test summary that you see
above is saved in the file
"/home/kgrittn/git/postgresql/kgrittn/contrib/dblink/regression.out".
