How about (untested!) something like this for clarity: 
BEGIN {
    eval "require 5.008; use open OUT => ':raw:perlio'; sub _binmode()
+ {}";
    eval "sub _binmode { binmode @_ }" if $@;
}

Then replace the binmode with _binmode and everything should happen automagically. The prototype will even cause these calls to be optimized away complete on Perls that don't need them.

Makeshifts last the longest.
