how to convert db4 mailboxes.db to db3 ?

[sandra]

Patrick,


   I have tried to do the conversion from db4 to skiplist for the
cyrus-imap
compiled with db4, but, there is a error message:


# ./cvt_cyrusdb mailboxes.db db4 mailboxes.skiplist skilist
fatal error: unknown old backend
Why doesnt it recognize db4? I have to compile with some other parameter,
like
--with-mboxlist-db=db4 ?

Thanks

Sandra
