Are you doing this from within ir.exe?  
gem/igem should be run directly from the command line and not from  
within ir.exe.  
Just want to see where you’re coming from executing this

Great! By the way, if rspec ends up being too heavyweight for what you  
are doing, you could also try bacon:  
(Installs through igem the same way rspec did)
