<--  snip  -->

# apt-get install aptitude dpkg
The following packages will be REMOVED:
  cyrus-imapd wine 
[answer n]
# apt-get install aptitude dpkg cyrus-imapd wine
The following packages will be REMOVED:
[answer n]
# apt-get install aptitude dpkg cyrus-imapd wine autoconf2.13 
[nothing to be removed]

<--  snip  -->

OTOH, at least in the woody installation I tried this,
"aptitude -f --with-recommends dist-upgrade" works fine.

It seems aptitude in woody has a better Conflicts handling than apt in 
woody making the first step easier for users.
