ok i try to describe in more detail the problem:
run this two command on centos's src.rpm:
rpm -qp --requires kernel-2.6.18-128.1.1.el5.src.rpm | grep unifdef
rpm -qp --requires kernel-2.6.18-128.1.6.el5.src.rpm | grep unifdef
now download rhel's src.rpm and run it on that rpms. the result are
different. while both rhel's src.rpm are required unifdef the latest
centos kernel do _not_ require unifdef. it has nothing to do with my
setup since all these files are downloaded from centos and rhel.
anyway see this bug report:
and if i build in mock i've got:
