PS. I would propose a specific fix but I can't seem to build a working CPython from the trunk on my laptop (OS X 10.6, Xcode 4.1). I get this error late in the build:
./python.exe -SE -m sysconfig --generate-posix-vars Fatal Python error: PyInitialize: can't initialize sys standard streams Traceback (most recent call last): File "/Users/guido/cpython/Lib/io.py", line 60, in make: *** [Lib/sysconfigdata.py] Abort trap
FWIW I managed to build Python 2.6, and a trivial mutation of the string/unicode hash function (add 1 initially) made only three tests fail; test_symtable and test_json both have a dependency on dictionary order, test_ctypes I can't quite figure out what's going on.
Oh, and an unrelated failure in test_sqlite:
File "/Users/guido/pythons/p26/Lib/sqlite3/test/types.py", line 355, in CheckSqlTimestamp self.failUnlessEqual(ts.year, now.year) AssertionError: 2012 != 2011
I betcha that's because it's still 2011 here in Texas but already 2012 in UTC-land. Happy New Year everyone! :-)
