[Dovecot] Compile error sieve plugin for dovecot2

[Christian Kivalo]

Hello,

I'm trying to compile the sieve plugin for dovecot2

Dovecot2-beta6 is allready running and working.

i did a hg clone http://hg.renamie-it.nl/dovecot-2.0-pigeonhole and ran the
autogen.sh script as mentioned in the INSTALL file

configure options:
/configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc
--with-dovecot=/usr/lib/dovecot/ --with-managesieve=no

compiling gives an error after a while:

/bin/bash ../../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I.

am i missing something? further information can be provided. dovecot2 was
configured with prefix/sysconfdir/localstatedir as above

it doesnt make any differences if i change --with-dovecot to the local sources
directory

thanks in advance
