apt-cache show libapache2-mod-php4 mi dice:

depends: libbz2-1.0, libc6 (>= 2.3.2.ds1-21), libcomerr2 (>= 1.33-3), 
libdb4.2, libexpat1 (>= 1.95.8), libkrb53 (>= 1.3.2), libpcre3 (>= 
4.5), libssl0.9.7, libzzip-0-12 (>= 0.12.83), zlib1g (>= 1:1.2.1), 
mime-support (>= 2.03-1), apache2-mpm-prefork (>> 2.0.52), php4-common 
(= 4:4.3.10-16), libmagic1

e come vedi figura apache2-mpm-prefork,
mentre apt-cache show libapache2-mod-php5

Depends: libbz2-1.0, libc6 (>= 2.3.2.ds1-21), libcomerr2 (>= 1.33-3), 
libdb4.2, libkrb53 (>= 1.3.2), libssl0.9.7, libxml2 (>= 2.6.16), 
libxslt1.1 (>= 1.1.12), zlib1g (>= 1:1.2.1), mime-support (>= 2.03-1), 
php5-common (= 5.1.2-1.dotdeb.1), libmagic1

non figura apache2, mentre ovviamente se non c'e' apache installare solo 
il modulo non avrebbe senso.
