Can you verify this behavior by doing a local deploy and running the svn  
build from a non merlin cmd prompt?

Optparse should be in the Libs folder with our hacks and such. If it’s  
not then something didn’t get pushed out correctly.

Copy optparse.rb from an MRI installation (i.e.  
lib/ruby/1.8/optparse.rb) into the same directory as ir.exe … I believe  
this worked for me when I was working on getting mspec running.

I am having trouble running the RubySpecs from rake.

First I get this:

D:\dev\ruby\ironruby\head\>rake mspec:lib

(in D:/dev/ruby/ironruby/head)

mspec/bin/mspec:141:in `exec’: No such file or directory -

```
    from mspec/bin/mspec:146

```

rake aborted!

Command failed with status (1): [ruby mspec/bin/mspec ci -t

(See full trace by running task with --trace)

It appears that ir.cmd is hard-coded inside rake to look in the release  
folder rather than debug, which is to where rake compile is building.

OK so I copy the files over from debug to release and now I get:

D:\dev\ruby\ironruby\head\>rake mspec:lib

(in D:/dev/ruby/ironruby/head)

d:\dev\ruby\ironruby\head\src\IronRuby.Libraries\Builtins\kernelops.cs:300:in  
`require’: no such file to load – optparse (LoadError)

```
    from :0:in `Initialize##1'

```

rake aborted!

Command failed with status (1): [ruby mspec/bin/mspec ci -t  
d:\dev\ruby\iro…]

D:/dev/ruby/ironruby/head/rakefile:351:in `invoke\_mspec’

(See full trace by running task with --trace)

I get the same result with rake mspec:core and mspec:lang.

Any ideas?
