kdepim (kmail) error: SASL authentication is not compiled into kio_imap4.

Tim, Serghei, Robert, all kmail is having problems getting to imap folders on my imap server. It sends over smtp just fine. My server uses SSL (Plain) for imap access. When I attempt to subscribe to folders on my server (or just open up the server settings), I get the following error: SASL authentication is not compiled into kio_imap4. How do I fix this? Which build flag/option needs to be set? Which package (kdebase?) -- David C. Rankin, J.D.,P.E.
