version conflict in freebsdports?

I have dovecot 2.2.33 installed. When trying to install dovecot2-pigeonhole (v 0.4.19) I get the following when it tries to install dovecot 2.2.31_1

I run portsnap fetch update daily, and I ran it again after this error, but same result.

===> Installing for dovecot2-2.2.31_1 ===> Checking if dovecot2 already installed ===> Registering installation for dovecot2-2.2.31_1 as automatic Installing dovecot2-2.2.31_1... pkg-static: dovecot2-2.2.31_1 conflicts with dovecot-2.2.33.2_2 (installs files into the same place).
