This method recorded every spec that was loaded even if no such gem  
was ever required.  I suspect that what's really wanted is  
Gem.loaded_specs.

How does rubyscript2exe work?  I can't find gatherlibs,  
Gem::Specification, anything:

$ gem unpack rubyscript2exe
Unpacked gem: '/Users/drbrain/tmp/rubyscript2exe-0.5.3'
$ ack gatherlibs rubyscript2exe-0.5.3/
$ ack Specification rubyscript2exe-0.5.3/
$ ack Gathering rubyscript2exe-0.5.3/
$

It seems to be constructed of magic feathers and fairy dust.

Oh, it seems to be that giant comment of base64 encoded data at the  
bottom, that's just mean.

Yeah, it should use Gem.loaded_specs:

$ grep -nA1 \.list require2lib.rb
60:      Gem::Specification.list.each do |gem|
61-        if gem.loaded?
