if depends on your needs. dovecot support IMAP METADATA Extension (RFC  
5464) out of the box.
at least I do not need a separate source package anymore.

I have this with dovecot-2.2.12:

--- snip
imap_metadata = yes
mail_attribute_dict = file:Maildir/dovecot-metadata
--- snap

together with "mail_location = maildir:~/Maildir"
dovecot create it's operational files at the usual location.
works perfect with my horde ...
