Well, a quick-and-dirty implementation looks like this - not much
detailed error checking, but it works. Creates a fake rockspec with
the desired dependencies and makes it.
The package name 'fake' is not right, someone may already be thinking
of assigning a good meaning to it ;) Besides, we should also remove
the fake package afterwards, to be tidy.

you put it together with the other commands

local tmpfolder = fs.make_temp_dir('fake')
local fake_rockspec_name = tmpfolder..'/fake-1.0-1.rockspec'
local fake_template = [[
