[racket-dev] Again. JPEG: unsupported library version: "unknown"

It's weird.
I cloned and modified the racket/draw/unsafe/jpeg.rkt, even the basic form
(ffi-lib "libjpeg")   gives me the unknown version, and the only version in
my system is 62. Finally I solved it by configuring with "--disable-libffi".


More over, I don't know the difficulties to have retina display supported
either.
Maybe it's time to do some researching on the source code.
