rpmbuild error with cups-1.2.4

[Norton Ji]

Hi,

I was trying to build a RPM package and i got the following error:
"rpmbuild -tb cups-1.2.4-source.tar.gz"

RPM build errors:
    File not found by glob: /tmp/cups-root/etc/dbus-1/system.d/*


with the option "--without dbus", the packages are created fine.
My system is a CentOS-4.3, x86, dbus-0.22-12.EL.5. If I just compile and install cups(configure;make;make install), I get no errors.
Any ideas?
