Problems with the build system

[José Matos]

All packages that I have queued today for development (soon to be FC-6...) 
give:

...
Executing /usr/sbin/mock-helper 
yum --installroot /var/lib/mock/fedora-development-i386-core-8bae10b92c20a2a004849117ea388cf7178fd75c/root 
install buildsys-build
file:///pub/fedora/linux/core/development/i386/os/Fedora/RPMS/sed-4.1.5-5.fc6.i386.rpm: 
[Errno -1] Header is not complete.
Trying other mirror.
Error: failure: Fedora/RPMS/sed-4.1.5-5.fc6.i386.rpm from core: [Errno 256] No 
more mirrors to try.
