I installed Virtualbox on Mac OS X to run newLISP on Linux UBUNTU 8.04

ps: when downloading virtualbox for Mac OS X, it comes with a .dmg.bz2 extension, strip off the b22, its just a normal .dmg disk image file.
You also have to install jre6 (or 5) from Sun. Install Java in /usr/java or anywhere else, but make a softlink into /usr/bin/java, e.g:
$ ln -s /usr/java/jre.6.0_06/bin/java /usr/bin/java
then start newLISP-GS from a terminal window with
$ newlisp-edit
To compile newLISP on UBUNTU you have to install two additional packages:
$ sudo apt-get install build-essential libreadline5-dev
