Can't install diskimage-builder via "pip install -e"

[Lucas Alvares Gomes]

We should be able to install diskimage-builder using "pip install -e"

ERROR:

stack@virtual-machine:~/devstack$ ramdisk-image-create
/usr/local/bin/ramdisk-image-create: line 35: /usr/local/bin/../lib/die: No such file or directory

HOW TO REPRODUCE:

$ git clone https://github.com/openstack/diskimage-builder

$ sudo pip install -e diskimage-builder

$ ramdisk-image-create -o test fedora
/usr/local/bin/ramdisk-image-create: line 35: /usr/local/bin/../lib/die: No such file or directory

    Handle install with pip -e

    As described in the comments, inspect the installation to see if we
    have been installed with "pip -e" and, if so, make sure we reference
    the scripts from the source location rather than the
    system-installations.

    Update the documentation with a terse but helpful quick-start to show
    an easy way to start developing a change using this.
