Running the same test file in both:
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
Python 3.1.1 (r311:74480, Feb 14 2010, 15:55:41)
python -m doctest test2.txt and
python3 -m doctest test2.txt
No failure in 2.6.2.
For 3.1.1:
File "test2.txt", line 9, in test2.txt
Failed example:
sys.stdout.write("This text\n contains weird spacing.")
# doctest: +NORMALIZE_WHITESPACE
Expected:
This text contains weird spacing.
Got:
This text
contains weird spacing.38

but with print() it works:
print("This text\n contains weird spacing.")
# doctest: +NORMALIZE_WHITESPACE

This doesn't have anything to do with NORMALIZE_WHITESPACE.
In python3, <file>.write returns the number of bytes written, instead of None. If you add the 38 to the end of your test line, the test will pass.
This is not a bug in doctest, but a difference in 'write' behavior between Python2 and Python3. You can write doctests that will pass on both by explicitly discarding the return value:
>>> _ = sys.stdout.write("xxxx").
xxxx
