Hi,
I read that, but I assumed it required the source to be unpacked. I tried it and I recieved the following error while trying to compile xen 3.2 srpm under CentOS 5.1x64:

error: Bad exit status from /var/tmp/rpm-tmp.42788 (%build)

Cleaning out the /var/tmp dir fixed it? Is that normal/fluke?

Thanks!
