xorriso : FAILURE when building iso-hybrid

["Dionisio E Alonso (Baco)" <dalonso@grulic.org.ar>]

I am building a system with Live Build version 4.0~alpha38-1

The system I'm trying to build is based on Sid distribution with options:

--debian-installer live
--distribution sid
--binary-images iso-hybrid
--debian-installer-distribution daily

When the system is building the image i get the following error:

  xorriso 1.3.2 : RockRidge filesystem manipulator, libburnia project.

  Drive current: -outdev 'stdio:live-image-i386.hybrid.iso'

Any idea on what am I missing to configure or install on my system in
order to overcome this error?
