In particular fixing things like environ.... see https://bugs.ruby-lang.org/attachments/2591/ruby-changes.patch for the kind of change you'll need to make, although I have to say the way they chose to do it is risky at best (but sadly typical).

The Ruby patch pointed to does not explain _why_ it is needed.
'environ' is required by the Single Unix Specification (at least
in issue 7; I don't have an earlier version handy just now).  And
it works just fine in MacOS 10.6 and did in 10.5 (32-bit and 64-bit).
