[sheepdog] Issues about setup

[hujianyang]

Hi Hitoshi,

I'm a learner of sheepdog. Here is two issues about setting
up sheepdog in my environment.

1) invalid option '-d' in README

"""
To set up a 3 node cluster using local driver in one liner bash with debug mode:

      $ mkdir /path/to/store
      $ for i in 0 1 2; do sheep -c local -d /path/to/store/$i -z $i -p 700$i;sleep 1;done
"""

but:

      $ sheep -c local -d /mnt/store/0 -z 0 -p 7000
      sheep: invalid option -- 'd'
      Try 'sheep --help' for more information.

Seems '-d' is removed so maybe README file should be updated?

2) compile error in version v0.9.0+

When compile sheepdog v0.9.0+, I met a lots of error messages
below:

I switch to use v0.8.3 and it's OK.

I'm not sure if it's a real problem or I miss something. I'd
like to show you the software version of my environment if it
is really needed.

Thanks for your help~!
