Thank you for the fix, I can build and install now.

Now I'm having issues with the example in the man page.

I'm getting unkonw option error for --host-bind:
> mkdir $HOME/scratch
> virt-sandbox -c lxc:/// --host-bind $HOME=$HOME/scratch /bin/sh
Unknown option --host-bind

The part in the man page for the options probably has typo.
-b DST-GUEST-DIR=SRC-GUEST-DIR, --guest-bind
One of them should probably be HOST-DIR?

-B DST-GUEST-DIR=SRC-HOST-DIR, --guest-bind DST-GUEST-DIR=SRC-HOST-DIR
Maybe it should be --host-bind?

When dropping the --host-bind option I'm getting permission denied error:
> virt-sandbox -c lxc:/// /bin/sh
Unable to open connection: Unable to open lxc:///: Failed to connect socket to '/var/run/libvirt/libvirt-sock': Permission denied

I've found this
http://wiki.libvirt.org/page/Failed_to_connect_to_the_hypervisor#Permission_denied
But it's not clear what to put in unix_sock_group, unix_sock_ro_perms and unix_sock_rw_perms.

When running as root I'm getting another error (or warning):
> sudo virt-sandbox -c lxc:/// /bin/sh
/bin/sh: 0: can't access tty; job control turned off

Thanks
