csc.exe is failing. Doing a web search,  
[http://support.liquid-technologies.com/KB/a42/application-fails-to-run.aspx](http://support.liquid-technologies.com/KB/a42/application-fails-to-run.aspx)  
mentions that your .NET installation may be corrupt. You need to figure  
out how to get the csc command to work on your machine. The failure is  
not related to IronRuby. Subsequent commands in the Cucumber example  
will fail only because Calculator.dll was not compiled successfully.

I got it to work by manually running csc.exe. It solved the problem.

Looks like the compile isn’t even working. This is a bit strange…Could  
you  
try getting cucumber from the git repo and try to compile from the  
examples  
dir there first?

Actually I got it to work by manually firing the csc.exe compiler to  
compile  
the Calculator.cs into an assembly. It works fine now!
