Me: Most venerated Gentoo system, I am interested in installing the package "kdebase-kioslaves". I have dutifully given all you ask. I have spent 4 days alone in compilitory supplication for your most current update -- and 7 days upon your installation not three months ago. I have wresteled with rev-dep demons and broken packages. I humbly beseech thee: What must I do to install this package?

Portage: Thou hast asked, and I shall let it be known, that there are three obstacles that must be overcome -- for the package kdebase-kioslaves-3.5* blocketh thy goal, as do the packages kdebase-3.5* and kdialog-3.5*.

Me: Verily, I shall do my best to overcome. Pray tell, great and noble Portage: What versions of these packages are installed upon the system, so that I might wrest them from power and cast them into the fiery pits of software deprecation?

Portage: My son, nowhere on the system are they installed.

Me: But... you just said...

Portage: You dare question me??

Me: No... well... pray tell, then, Mighty portage, can you list all the packages installed upon thy system?

Portage: You have shown great diligence in your quest faithful one. I shall grant thee this boon. *emerge -epv world is executed and a list of more than 440 packages are shown*

Me: But.. great and Mighty portage, I have sifted though thy generous bounty, and find not these three packages to be installed...

Portage: It is just so.

Me: But...

Portage: Accept this paradox as the mystery of Gentoo.

Me: But... I have to get this working! I worked so hard on this. Weeks I have slaved!

Portage: Well, then, I guess you are SOL then, aren't you?

Me: Huh? WTF? This sucks... are you telling me that's it?

Portage: Yep.

Me: But...

Portage: *shrugs*
