I have fixed the permission issues which were just due to the setup I was using.

Without redis installed there are now just 4 xfailures:

XFAIL test/test_anydbm.py::anydbmDBTest::testEmptyCreate - Create class w/o key field and no properties is undefined.
XFAIL test/test_mailgw.py::MailgwTestCase::testEmailQuotingRemove3 - OK: sig not removed - delim not first section line
XFAIL test/test_memorydb.py::memorydbDBTest::testEmptyCreate - Create class w/o key field and no properties is undefined.
XFAIL test/test_sqlite.py::sqliteDBTest::testEmptyCreate - Create class w/o key field and no properties is undefined.
