Ahh I see. I don't have a copy of 1.8.6 handy to test on, but this definitely fails for MRI 1.9. It seems like getting the binding of an ostruct in 1.9 doesn't work for evaluating local variables. Perhaps they changed ostruct?
Here's what happens for me:
irb(main):020:0> ostruct = OpenStruct.new({:foo => 'bar'})
=> #<OpenStruct foo="bar">
irb(main):021:0> ostruct_binding = ostruct.send(:binding)
=> #<Binding:0x2545dd0>
irb(main):022:0> eval("foo", ostruct_binding)
NameError: undefined local variable or method `foo' for main:Object
IronRuby 1.1 aims for compatibility with ruby 1.9 (and ships standard
libraries such as ostruct from 1.9 also), so it is designed to fail with
the same errors as MRI 1.9
I'm not sure what you can do to work around it, all the best.

I am trying to send the binding of the OpenStruct object not the binding
of main. I have been using this with MRI 1.8.6 for some time and works
fine.

I notice that in your example, you don't declare the local variable foo
anywhere:
If I run it verbatim, both MRI and IronRuby fail with undefined method foo
(and fair enough, foo isn't defined).
When I declare foo as a local variable, both MRI and IronRuby work fine
for me.

I am using OpenStructs and ERB for template generation. In this simple
example, ruby 1.8.6 runs this fine:
require "erb"
require "ostruct"
puts ERB.new("<%=foo%>", 0, "%<>").result(OpenStruct.new({ :foo => "bar"
}).send(:binding))
However, it generates the following error when I run this in IronRuby
1.1.3.0 on .NET 4.0.30319.269:
(erb):2: undefined method `foo' for main:Object (NoMethodError)
Does anyone know how to get this to behave correctly in IronRuby?
