I’m also wondering what will happen if you put the gem on two different gem 
servers (if that is possible, like github and rubyforge). Does gem attempt all 
sources to find the most specific? Or does it go with the most specific gem 
from the first source?

Will, could you recreate the universal-.net gem again and push it? I think it 
might have been created incorrectly. The persisted Gem::Specification has 
@new_platform and @original_platform set to “universal-unknown” which might 
happen if you create it with MRI as I had mentioned below…

My guess is that RubyGems tries to look for an exact platform match first. If 
there is no exact match, it somehow prefers “ruby” over other platforms.

Btw, you could just change clr_version in 
Merlin\Main\Languages\Ruby\Libs\rbconfig.rb to “4.0” to simulate running on 
.NET 4. After doing this and using the “—platform universal-.net” option, 
iron-term-ansicolor-0.0.3-universal-.net-2.0 was installed which was surprising 
to me as I would have expected it to install 
iron-term-ansicolor-0.0.3-universal-.net. When I used the “—platform 
universal-.net-4.0” option, iron-term-ansicolor-0.0.3 was installed which was 
also surprising. So there does not seem to be any way to install 
iron-term-ansicolor-0.0.3-universal-.net.

Thanks, Daniele!

I've got three version of iron-term-ansicolor out there on RubyGems.org:


  *   iron-term-ansicolor-0.0.3                     (gemspec.platform="ruby")
  *   iron-term-ansicolor-0.0.3-universal-.net      
(gemspec.platform="universal-.net")
  *   iron-term-ansicolor-0.0.3-universal-.net-2.0  
(gemspec.platform="universal-.net-2.0")

It looks like the .Net 4 runtime selected the non-platform specific gem, while 
the .Net 2 runtime selected the "universal-.net-2.0" gem.
