Indeed, it does that already!

I linked here in another post a page that should have been an
introductory guide to write makefile-less rocks, but maybe it is not
clear or detailed enough (or maybe it tries to cover too much ground
at once, I don't know -- I'm probably in too deep into the thing to
discern between what's basic and what isn't). Anyway, here it is:
http://www.luarocks.org/en/Creating_a_rock

But I think some real examples would serve as a better demonstration
than that page, actually. Here are the rockspecs for:

* stdlib, a pure Lua rock:
http://luarocks.luaforge.net/rocks/stdlib-4-2.rockspec

* lpeg, uses C code (notice that lpeg ships a makefile, but we just
don't use it!)
http://luarocks.luaforge.net/rocks/lpeg-0.8.1-1.rockspec

* luagl, uses C code, links to external libraries, and still no makefiles used!
http://luarocks.luaforge.net/rocks/luagl-1.01-1.rockspec

* for contrast, here's the one for luafilesystem, which does uses
makefiles and handles unix/windows portability issues:
http://luarocks.luaforge.net/rocks/luafilesystem-1.4.1-1.rockspec

Rocks tries to follow the "keep simple things simple, make complex
things possible" approach.

Actually, you can. Looking at the luafilesystem example linked above.
You can specify different types on each platform section. But the
"module" type should work on Windows as well. (You may need to specify
different library names, though, but it should be possible -- if you
bump into any LuaRocks shortcomings in this regard we'd certainly like
to hear about it at the LuaRocks mailing list.)
