Hello,

I installed IronRuby 0.3.0 from github and ruby 1.8.6 on my windows xp  
machine.  
Further I installed the gem sinatra using ruby and edited the  
ir.exe.config so that the ruby libraries get loaded.  
When I start ir and type require ‘rubygems’ everything works fine.  
When I type require 'sinatra# I get the following error:

(eval):3:in `load_specification': private method`specification\_version=’ called  
for #\<Gem::Specification name=abstract version=1.0.0\> (NoMethodError)  
from specification.rb:406:in `initialize' from (eval):0 from :0:in`eval’  
from source\_index.rb:89:in `load_specification' from source_index.rb:127:in`load\_gems\_in’

Thx a lot.

It worked for me with the latest sources. “gem i sinatra” installed  
version sinatra-0.9.1.1. The issue was probably fixed independently.  
Thanks for reporting anyway.

If you want to build the latest version yourself and try again,  
[http://wiki.github.com/ironruby/ironruby](http://wiki.github.com/ironruby/ironruby) has the info you need.

Thanks,
