This bit from your log:

"""
The following packages have unmet dependencies:
  apache2-mpm-prefork: Depends: apache2.2-common (= 2.2.16-6+squeeze4)
but 2.2.16-6+squeeze6 is to be installed.
                       Depends: apache2.2-bin (= 2.2.16-6+squeeze4)
but 2.2.16-6+squeeze6 is to be installed.
  apache2: Depends: apache2.2-common (= 2.2.16-6+squeeze4) but
2.2.16-6+squeeze6 is to be installed.
The following actions will resolve these dependencies:

     Remove the following packages:
1)     apache2
2)     apache2-mpm-prefork
3)     libapache2-mod-perl2
4)     libapache2-reload-perl
"""

suggests maybe you need to run "aptitude update" to get your packages
in sync. http://packages.debian.org/search?keywords=apache2-mpm-prefork
says you should be getting 2.2.16-6+squeeze6.
