Revisar Dependencias con apt-rdepends

Esta es una corta guía que muestra como revisar las dependencias de un paquete con la herramienta apt-rdepends en Debian y Ubuntu. Lo mejor de apt-rdepends es que resuelve las dependencias recursivamente, no solo muestra las dependencias directas del paquete, también las dependencias de las dependencias. Esto es bueno si es que deseas reconstruir (rebuild) un paquete desde las fuentes.

Este documento viene sin ninguna garantía de que funcione en tu casa. (Nota del autor)

apt-rdepends

Para instalar apt-rdepends, simplemente ejecuta:

apt-get install apt-rdepends

Después, ya lo puedes usar para resolver dependencias. Para aprender como usarlo, puedes darle una mirada a

man apt-rdepends

Usualmente solo lo usas con un nombre de paquete, ejemplo apt-rdepends "paquete", por ejemplo para revisar las dependencias del paquete libapache2-mod-php5, ejecutas

apt-rdepends libapache2-mod-php5

Este es un ejemplo de la salida desde un sistema con Debian Etch:
