Visualice dependencias de binarios y librerías en Linux
Leí un post sobre hacer esto y me pareció buenísimo les dejo un par de imágenes en los que se puede visualizar gráficamente las dependencias de binarios fácilmente, lo unico que necesitas es Graphviz (http://www.graphviz.org/).
Mira los ejemplos que hize
binario emacs:
binario de konqueror:
