i'm working on rebasing and updating this

[fkautz]

@avadacatavra a few updates which may help you

• hyper 0.10 was released, removes deps on cookie and openssl packages
• websocket still depends on openssl 0.7 and cookie 0.2
• cookie 0.2 depends on openssl 0.7, but cookie 0.4 and above already have openssl 0.9 support

[edit: said webdriver package but meant websocket, updated comment directly]

Not much point in leaving this open. @avadacatavra will open a new PR, presumably.
