pilerimport mysql_stmt_execute errors on XStreamOS/illumos

[Gabriele Bulfon]

Hello,
I've ported Piler on our XStreamOS / illumos distro.
Running pilerimport against our imap server on an example user, I find all of 
this messages in syslog:
[ID 981359 mail.info] 4000000055a637ef348ee714009ebbd6c280: mysql_stmt_execute 
error: *Incorrect arguments to mysqld_stmt_execute* (errno: 1210)
on for every message it tries to import.
Any idea?
Gabriele.
