[Dovecot] dovecot 2.0beta4 zlib

Hello,

When trying to enable the zlib and imap_zlib plugins, I get the following error: imap: dovecot/imap:/opt/dovecot/lib/dovecot/lib2 0_zlib_plugin.so: undefined symbol 'i_stream_create_bz2'

I did not compile it using --with-bzlib though and bz2 libs are available on the system.

Best Regards
