5.10.1 is hardly "too old" :)

This is a harmless error, just ignore it. The test itself has been 
relegated to xt/ as it gives user-inactionable false negatives sometimes.

I am not sure - never seen this one. Perhaps try an older DBD::SQLite 
first (e.g. 1.37). It seems to be related to the ordering changes...
