This appears to be a result of the following mono bug:
https://bugzilla.novell.com/show_bug.cgi?id=541823

The specific issue is that the regex:
(?-six:\A[\s]*(=|!=|>|<|>=|<=|~>)?[\s]*([0-9]+(\.[0-9a-zA-Z]+)*)[\s]*\z)
Does not match ">= 0" in mono but does match on .NET

This is a mono bug, not an ironruby bug.
