I've installed a fresh CentOS 5.0 (x86-64) and did: (1) Create ~/.rpmmacros & ~/rpm directory structure as described in Dan's email. (2) yum install rpm-build rpm-devel python-devel xen-devel \ libxml2-devel readline-devel ncurses-devel gnutls-devel \ gcc (3) wget ftp://libvirt.org/libvirt/libvirt-0.3.2-1.src.rpm (4) rpm -i libvirt-0.3.2-1.src.rpm [NB: NOT as root] (5) cd ~/rpm/SPECS; rpmbuild -ba libvirt.spec [NB: also NOT as root] and it rpmbuilds just fine. So I suspect that your problem was because you were trying to rpmbuild as root, which as mentioned before is dangerous anyway.
