Can you list the mailbox file?  [are you sure it isn't a permissions
problem]

A much better option is to use cvt_cyrusdb on the running server to
convert the databases to skiplist and then use those databases over on
the new server.  Generally people have migrated away from BDB [in large
part because of issues like these; getting a reliable build environment
is tedious].

Example:
su cyrus -c "/usr/lib/cyrus-imapd/cvt_cyrusdb \ 
  /var/lib/imap/mailboxes.db berkeley /tmp/mailboxes.db skiplist"
