Managesieve stopped working - Undefined symbol "i_stream_read_memarea"

[Henrik Larsson]

After upgrading Dovecot to 2.3.2.1 and Pigeonhole to 0.5.2, managesieve 
stopped working.

I'm using FreeBSD ports tree, to build these. Only domains have been 
modified in below output.

A FreeBSD bug report have also been created. But I'm not sure if this is 
FreeBSD ports related or Dovecot/Pigeonhole related:
