All Unixes and unix-like systems are a little different because they
*are* a collection of little tools. OSX has it's underpinnings from
different sources than Linux due to licensing and Steve Jobs being,
well, Steve Jobs. Anyway, what you'll find is in some cases it's much
closer to BSD than GNU tools used in GNU/Linux (every "Linux" except
Android). I know that doesn't make a hill of beans difference to you
right now but make no mistake: OSX is certified UNIX. GNU/Linux is
not. OSX adheres to standards that "Linux" does not.

I'd like to point out that sudo is no different than having to type in
your password before you install something from the app store or buy
something with your paypal account. It is a means to prove credentials
and elevate privilege in Unix.
I'm not sure if this has been suggested, but you Lua can be run from
within the src directory where it was built or be put pretty much
*anywhere* that you have access. If you don't want to bother
installing it system wide (which requires sudo!), then alter the
makefile (that installs Lua) to point to your local home directory and
install it there (~/bin perhaps?). Then you add that path to your
shell initialization and it's always available to YOU but it's not
available to anyone else. On a Mac Laptop or PC, that isn't really an
issue I suspect. I'm sure if you ask, someone on the list can help out
with the commands if you figure out what shell your using. Dirk can
provide a link to that I think? (Also another joke, just Google it).

It seems to me you are experiencing the same response that 99% of us
do when faced with a new challenge. I've been using computers
literally my whole life and I still *seethe* when doing something new.
I want to throw my computer (I know, I need help) because they are
so... impossibly... complicated! Keep persisting. It pays off.
Some advice since you didn't ask:
- PIL 4 is a fantastic book. If you know what a loop and a variable
is, start at Page 1 and follow the examples. Otherwise, learn what a
loop and a variable is and then start at page 1. ;)
- Read some Unix history and start at the basics by learning to follow
man pages (short for Manual because people in Unix hate typing. tee
hee, that's a joke.). Man pages are also something that is *totally
infuriating* until you "get it" and then it's good. I find them
easiest to read online, but have never looked for OSX man pages (I
mostly use FreeBSD).
- KEEP NOTES. Write down all your commands and come back to it and
update it. Those notes will become invaluable and if you persist will
likely turn into "shell scripts".
- Follow KHMan's advice (pretty much the same as keep notes). Start a
temp directory (mkdir ~/temp/) and dump your work in there until it's
worth keeping. As for GUIs, ZeroBrane is a fantastic way to learn Lua.
There are a TON of great examples. Geany and Scite are both good free
GUI editors that support Lua syntax highlighting but don't support a
Lua debugger out of the box.
Hope that helps. :)
