I am sorry that you are struggling with this. One option is to use an older, officially-supported version of Ubuntu.
That said, it worked for me on Ubuntu 14.04 64-bit. But please make sure you have all these packages installed on your host:
# from "Setting_Up_LTIB_host.pdf" included in BSP Docs
echo "Loading Min Packages for LTIB"
echo "LTIB 1/3: needed by LTIB"
sudo apt-get -y install gettext libgtk2.0-dev rpm bison m4 libfreetype6-dev
sudo apt-get -y install libdbus-glib-1-dev liborbit2-dev intltool
sudo apt-get -y install ccache ncurses-dev zlib1g zlib1g-dev gcc g++ libtool
sudo apt-get -y install uuid-dev liblzo2-dev
sudo apt-get -y install tcl dpkg
sudo apt-get -y install asciidoc texlive-latex-base dblatex xutils-dev
echo "LTIB 2/3: for 64b Ubuntu"
sudo apt-get -y install ia32-libs libc6-dev-i386 lib32z1
sudo apt-get -y install
sudo apt-get -y install
echo "LTIB 3/3: recommended"
sudo apt-get -y install gparted emacs22-nox openssh-server
sudo apt-get -y install nfs-common nfs-kernel-server lintian
sudo apt-get -y install git-core git-doc git-email git-gui gitk

sudo apt-get -y install sendmail mailutils meld atftpd sharutils
sudo apt-get -y install manpages-dev manpages-posix manpages-posix-dev linux-doc
sudo apt-get -y install vnc4server xvnc4viewer
Rod.
