Thanks for the tip... not sure if I needed more tools or not, but would rather have them than get to a later point in the Typo3 install script and find I did, LOL.
Having a bit of fun. Seem to be getting around a bit better, more comfortable with Terminal, editing that script a bit, etc. Thanks for the help
PS. As an update, in the future, prior to trying to run the Typo3 install script, I would run these terminal commands first...
sudo apt-get install build-essential
sudo apt-get install Re2c
sudo apt-get install bison
