When I do:

    env := Smalltalk environ .

I get the following:

Object: SystemDictionary new: 512 "<0x40290818>" error: did not
understand #environ
MessageNotUnderstood(Exception)>>signal (ExcHandling.st:254)
SystemDictionary(Object)>>doesNotUnderstand: #environ (SysExcept.st:1407)
SystemDictionary(BindingDictionary)>>doesNotUnderstand: #environ
(BindingDict.st:181)
UndefinedObject>>executeStatements (test-cgi.st:13)


I'm sure there is something wrong with my Smalltalk code
as well as probably missing something in what I did to add environ.

One thing is that environ is a variable, not a function, maybe they
are handled differently ?
