The missing overload for Regexp.new is the one that takes two string  
parameters, the second parameter represents the options and need not be  
an integer, if the options is not false then the regexp will be case  
insensitive.

The required patch is something like:

[RubyConstructor]  
public static RubyRegex/_!_/ Create([NotNull]MutableString/_!_/ str,  
object options) {  
return new RubyRegex(str,  
RubyRegex.ToClrOptions(Protocols.IsTrue(options) ?  
RegExOptions.IGNORECASE : RegExOptions.NONE));  
}

Cheers, Wayne.
