Upgrading pngquant (nasty error)

[opendaddy at hushmail.com]

Hi!

Getting this nasty warning here:

    WARN: pngquant 2.0.0 at /usr/local/bin/pngquant (< 2.1) may be lossy even with quality `100-`

Any chance we could upgrade the port?

Trying to use image_optim (https://github.com/toy/image_optim) with Discourse in Ruby on Rails (https://github.com/discourse/discourse):

Many thanks!

O.D.
