not ok 1 - Default checksum

This is due to row count differences in 5.1 vs. 5.5. Also, the 5.1 sandbox data has useless rows in mysql.db, maybe other tables, too. I need to rewrite pt-table-checksum basics.t to avoid these idiosyncrasies.

Was fixed again. A rouge local $EVAL_ERROR was suppressing the warnings the tests were wanting.
