From what I can gather, the regular ('old') way doesn't support
Lookbehind, but Oniguruma does, so:
[rosco@jukebox dev]$ irb
irb(main):001:0> "ab" =~ /(?<!a)b/
SyntaxError: compile error
(irb):1: undefined (?...) sequence: /(?<!a)b/
from (irb):1
irb(main):002:0> quit
[rosco@jukebox dev]$ irb9
irb(main):001:0> "ab" =~ /(?<!a)b/
=> nil
irb(main):002:0> "db" =~ /(?<!a)b/
=> 1
would appear to do it.

Umm, don't know.
