nunca he sido muy aficionado a linux pero esta aplicacion como que me ha picado un poco y queria instalarla, fuerte coñazo por cierto pues despues de media hora sigo con el mismo error xD.
cosas de novatos supongo
el caso es que introducir el ./configure --enable-plugins --enable-debug
o cualquier variante me da un fantastico configure: error: not found , y esta empezando a romperme los nervios.  es un error conocido pues encuentro miles de post con el problema pero la solucion no aparece, prove instalando unos repositorios para compilar en ubuntu pero nada,  el .tar del ettercap me lo descargue de souerceforge y el archivo descomprimido se llama ettercap-NG-0.7.3

root@XXXXXXXX:/home/xxxxxxx/Descargas/ettercap-NG-0.7.3#

busque en synaptic y con ese nombre concreto no habia ninguna, las habia parecidas , instale lo que me aparecio, vuelvo al ./configure y me da el mismo error.

alguna sugerencia???.   gracias

como ago para que cuanto instalo un paquete se instale automaticamente todas sus dependencias??? porque creo que es lo que me falla ,, graxx

si usas un gestor de paquetes tipo yum, apt pues las dependencias se resuelven y se instalan solas, si lo compilas a mano con configure, make, make install debes tu instalar los paquetes que te faltan.

Podias decirnos cula es el blog del que hablas?
Yo extoy teniendo muchos problemas con el ettercap en version64 bits
