[Dovecot] Dovecot 2.0 RC1 and OpenBSD 4.7

[D F]

Hello all,

I'm currently doing some tests with Dovecot 2.0 RC1 and OpenBSD4.7 (socppc
or i386 architectures) and I can't compile it :
I "./configure" with default options and then "make" :

$ make
[...]
Making all in doc
Making all in man
make: don't know how to make doveadm.1. Stop in
/home/mail/dovecot-2.0.rc1/doc/man.
*** Error code 1

Stop in /home/mail/dovecot-2.0.rc1/doc (line 386 of Makefile).
*** Error code 1

Stop in /home/mail/dovecot-2.0.rc1 (line 505 of Makefile).
*** Error code 1

Stop in /home/mail/dovecot-2.0.rc1 (line 328 of Makefile).

Is there any thing I can try ?

Thank you in advance,
Denis
