Trying to migrate from cyrus to ZCS on a clean install of 8.04LTS.

Using imapsync, it throws some errors:

Use of uninitialized value in quotemeta at /usr/bin/imapsync line 1113.
...
...
...
(repeated)

Followed By:

From Folder [user.user1] does not exist yet
From Folder [user.user1.Reported_Spam] does not exist yet
From Folder [user.user2.Trash] does not exist yet

This repeats for all users in the cyrus store.

I instantiated imapsync with the following call:

imapsync --nosyncacls --syncinternaldates --host1 mailhost.domain.edu --ssl1 --port1 993 --authmech1 PLAIN --user1 cyrus --password1 xxxxxxxx --prefix1 INBOX. --host2 zimbra.domain.edu --prefix2 INBOX/ --ssl2 --port2 993 --authmech2 PLAIN --user2 admin --password2 xxxxxxxx

What am I missing?
