Lua 5.1, MacOSX, and readline

[Gavin Kistner <gavin@...>]

I'm trying to get Lua 5.1 working with readline on MacOS X (10.4.5).  
Unfortunately, it's been over 10 years since I programmed in C, and  
though
 * I've seen posts claiming that MacOS 10.4 has readline installed  
by default...
 * I've downloaded and built gnu readline 5.1 successfully to get it  
working with Ruby's 'irb'
 * I've tried the make command listed here: http://lua-users.org/ 
lists/lua-l/2006-01/msg00200.html
 * I've tried copying the readline-5.1 src into lua-5.1/src/readline  
and lua-5.1/readline, while adding the LUA_USE_READLINE #define to  
luaconf.h
...all of the above failed. Really I'm just stabbing in the dark.

Can someone provide the explicit instructions that someone who hasn't  
used *any* compiled language since 1998 needs to build lua 5.1 with  
readline support under MacOS X v10.4.5? I don't really care if it's  
using Apple's own readline, pseudo-readline lib, or building and  
using gnu readline 4.0 or 5.1. I'd just like the fscking up-arrow key  
to work in the command-line lua interpreter. (Getting the 'advenced'  
readline patch to work for fun autocompletion is an optional bonus.)

Obviously I'm willing to try stuff out and report the results, if  
only you'll guide me. Thanks in advance. :)
