That was easy: "sudo port install luarocks".  Thanks, according to  
macports, are due to Andrea Damore.

Yep, I understood that.  I'm just trying to be lazy.  LUA_INIT looks  
like the way to go

$ LUA_INIT="require'luarocks.require'" lua
Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio

(no error!)

I can't quite work out how to do this in a rockspec and certainly not  
cross platformly, but it seems that a link is needed from ...luarocks 
\rocks\markdown\...\lua\markdown.lua to ...\luarocks\bin\, and  
permissions on markdown.lua need a "+x".  Then it turned out that OS X  
barfed on the "#!/usr/bin/env lua" because markdown.lua had windows  
line ends.  It's all working now though!
