[rsbac] rsbac_menu error!

[condor_rl@libero.it]

Hi,
I have downloaded an RSBAC pre-patched kernel form the official site,
exactly it is the:
linux-2.6.11.11-rsbac-1.2.5-pre1-pax-200503071330.tar.bz2

I have configured, compiled and instaled it.
Than I downloaded the Administartion tools:

rsbac-admin-1.2.5-pre1.tar.bz2

I compiled it and all goes well.

But when I boot using the RSBAC kernel and I try to execute the
"rsbac_menu" i give me back the following error:


deb-rsbac-vm:/usr/src/lo# rsbac_menu
/usr/local/bin/rsbac_menu: line 57: dialog: command not found
dialog menu program required!

What does it meani? Where I'm wrong? Do you have any suggestion ?

Thks 
Lorenzo
