As an example of a source code packaging system with gentoo:

emerge -C apache   <-- to remove
emerge -u apache   <-- to build new, uninstall old, and upgrade to new

Handling of the source there was done automatically.  But it is different
doing things manually from tarballs without any packaging system.

If you install it directly from a tarball and not from a package, you know
where your source files are, because you kept track of it all, right?  
Sometimes overwriting older versions of software will do the trick.  But 
sometimes older libraries will be looked up first by the new software.  It 
gets interesting when dealing with hundreds of packages.  One of them 
might play a game with you.
