It's a bit awkward, but there's a way to do it with my script library:

http://redshift.sourceforge.net/script/

Quoting the docs:
==========
An "input" can be passed to the script before loading. Simply call 
Script.new (or Script.load) with a block. The block is passed a single 
argument, the Script module, and executed before the files are loaded 
into the Script’s scope. Setting a constant in this block makes the 
constant available to the script during loading. For example:
   script = Script.load("my-script.rb") { |script| script::INPUT = 3 }
==========

The file "my-script.rb" would simply refer to INPUT. You can pass any 
number of args this way. See the "program2.rb" in the examples/ dir for 
an example.

As a bonus, everything defined in "my-script.rb" is wrapped in a module, 
returned by Script.load, and (in the case above) stored in a local 
variable in the main file, which you can use to access the constants and 
methods defined in my-script.rb.

HTH.
