Another plug towards gentoo, the dependency management is fairly good.
I have not had any issues with it, however I for the most part avoid
testing/unstable packages.  Also, you have the ability to compile a
package, insert a stub and have portage know about it.  In other words,
if you're system has an anchient perl5 and you want perl5.8, you can
pull it down, and stub the package and not have it break the whole
apt/dselect system.
