I saw 3.1a14 just now.  The diffs between 3.1a11 and 3.1a14 is not so
big.  I'll send above patch to the author.
It seems return code of ka_lookup() was changed during 3.1a11 and
3.1a14.  3.1a14's ka_lookup() returns 0 on success or -1 on error.
3.1a14's ka_lookup() returns 1 on success or -1 on error.
