sieve is built against dovecot not with dovecot...
download it from:
http://www.dovecot.org/releases/sieve/do...1.6.tar.gz
you compile with:
Code:
./configure --with-dovecot=<see below>
make
make install
--with-dovecot has to point to the directory containing the dovecot-config file (when installing the according -dev package ubuntu and I guess thus debian puts this into /usr/lib/dovecot)
What did you actually install? Where have you got this 1.1.9 from? Because debian normally builds the sieve plugin...
