php 5.3 на debian lenny

Пытаюсь обновить PHP с 5.2 до 5.3, но не понимаю что нужно сделать:(

root:~# apt-get install php5

php5 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

подключил репозиторий с 5.3 вроде ок(прописал там GPG ключи), обновился apt-get update'ом.

sources-list:

deb http://security.debian.org/ lenny/updates main contrib
deb-src http://security.debian.org/ lenny/updates main contrib

deb http://volatile.debian.org/debian-volatile lenny/volatile main contrib
deb-src http://volatile.debian.org/debian-volatile lenny/volatile main contrib

deb ftp://mirror.yandex.ru/debian/ lenny main contrib non-free
deb http://download.virtualbox.org/virtualbox/debian lenny non-free
deb http://security.debian.org/ lenny/updates main
deb http://packages.dotdeb.org lenny all
deb-src http://packages.dotdeb.org lenny all
deb http://php53.dotdeb.org stable all
deb-src http://php53.dotdeb.org stable all

ну и пробую upgrade говорит такое...

Need to get 1627kB of archives.
After this operation, 45.1kB of additional disk space will be used.

в итоге обновился как-то случайно с php 5.2.x lenny до dotdeb'a...

root:~# php -version
