[Ltib] ltib installation problem

[Giuseppe]

Hi all,
i'm trying to install LTIB for configure my kernel for imx53 QSB board.
I want install ubuntu with driver for SIERRA SL8092 modem HSPA.
I'm newbie. How i can do?
thanks
i have this error when i write./ltib:

I ran the command: sudo -S -l which returned:

Matching Defaults entries for giuseppe on this host:
    env_reset

User giuseppe may run the following commands on this host:
    (root) NOPASSWD: /usr/bin/rpm, (root) /opt/freescale/ltib/usr/bin/rpm
    (ALL) ALL

This means you don't have sudo permission to execute rpm commands as root
without a password.  This is needed for this build script to operate correctly.

To configure this, as root using the command "/usr/sbin/visudo",
and add the following line in the User privilege section:

giuseppe ALL = NOPASSWD: /usr/bin/rpm, /opt/ltib/usr/bin/rpm
