It does seem to.
Ruby Gems maintains a list of platform mappings.
See lib\ruby\site_ruby\1.8\rubygems\platform.rb in the initialize method.
Whatever initializes Gem::Platform seems to look at RUBY_PLATFORM
C:\IronRuby\bin>ir
IronRuby 0.9.4.0 on .NET 2.0.50727.4927

>>> require 'rubygems'
=> true
>>> Gem::Platform.local()
=> #<Gem::Platform:0x1ec @cpu="x86", @os="mswin32", @version="60">
>>> RUBY_PLATFORM
=> "i386-mswin32"
>>> p = Gem::Platform.new('universal-.net-3.5')
=> #<Gem::Platform:0x1ee @cpu="universal", @os=".net", @version="3.5">
