I have a question regarding packages repository in Debian (Lenny). A new server at rackspace cloud service comes with nothing (plain system) so i had to upgrade system and install all necessary packages by myself. But the problem is that default repositories does not provide newer versions of software i need (PHP is 5.2.6, comparing to 5.2.13). In CentOS i used to get all new packages from third-party sources, which works really well till now. I have talked to guys from rackspace about it and looks like they cant provide anything except kernel headers. And i dont really want to build from source.
So, whats the way to get newer software ? Any good third party sources?
