make fetch gives the same error

Okay, so here's what I did:

mkdir -p /usr/src/foobar/jason
cd /usr/src/foobar/jason
wget http://jgh.devio.us/files/libvirt.shar.txt
sh libvirt.shar.txt

This outputs:

c - libvirt/
x - libvirt/Makefile
x - libvirt/distinfo
c - libvirt/files
x - libvirt/files/patch-src__util__command.c
x - libvirt/pkg-descr
x - libvirt/pkg-plist

Then:

cd libvirt
make fetch

This outputs:

===>  Vulnerability check disabled, database not found
===>  License accepted by the user
=> libvirt-0.9.1.tar.gz is not in /usr/src/foobar/jason/libvirt/distinfo.
=> Either /usr/src/foobar/jason/libvirt/distinfo is out of date, or
=> libvirt-0.9.1.tar.gz is spelled incorrectly.
*** Error code 1
Stop in /usr/src/foobar/jason/libvirt.
