> Do you get different results if you pass --without-recommends as a command-line option?

Yes, that seems to do the trick!

#  aptitude --without-recommends install horde3
[...]
The following NEW packages will be automatically installed:
  php-db php-http php-log php-mail php-net-smtp php-net-socket
  php-pear php-xml-parser php4-common php4-pear
The following NEW packages will be installed:
  horde3 php-db php-http php-log php-mail php-net-smtp php-net-socket
  php-pear php-xml-parser php4-common php4-pear
The following packages are RECOMMENDED but will NOT be installed:
  php-date php-file php-mail-mime php-services-weather php4-gd
  php4-ldap php4-mcrypt php4-mysql php4-pgsql php5-gd php5-ldap
  php5-mysql php5-pgsql
[...]

So one of the recommends must be depending on or recommending apache
1.3, right?  I've played a bit around with apt-cache --recurse depends
but I couldn't figure out the culprit (at least not in 3 minutes :-)

It seems like I might to add the --without-recommends into apt.conf.

Thx!
