Install and configure sheepdog

Hello Guys,

I have general question, do you have some guide how to setup sheepdog ("https://github.com/sheepdog/sheepdog") on Alpine, is this in plan on future releases?
I tried setup on Alpine 3.3, used next dependencies:
##########################################
apk add corosync userspace-rcu userspace-rcu-dev corosync-libs git yasm libtool make autoconf automake gcc bash g++ alpine-sdk musl libusb python linux-headers
##########################################
And did next steps:
- Installed dependencies described upper
- git clone https://github.com/sheepdog/sheepdog/ /usr/src/sheepdog
- cd /usr/src/sheepdog/
- ./autogen.sh - no errors in this case
- ./configure - no errors in this case
- make check - got next issue:
##########################################
/usr/src/sheepdog # make check
