upon discovering the 10.6.0 32 bit newlisp is not happy on a 64 bit system.
I set about googling errors until the following cookbook Install of newLISP 10.6.2 worked clean on several 64bit Ubuntu 64bit 14.04.01 systems.
# Install newLISP 10.6.2 on amd64 ubuntu 14.04.01
sudo su
cd ~
apt-get install libreadline6 libreadline6-dev libffi-dev
wget http://www.newlisp.org/downloads/development/inprogress/newlisp-10.6.2.tgz
tar -xvf newlisp-10.6.2.tgz
cd newlisp-10.6.2/
./configure
make
make install
# done now Test in teminal:
cd ~
newlisp
# returns
newLISP v.10.6.2 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h

Good luck ...
