The hdparm source RPM fails to rebuild, and cannot be built as a normal user. There are two problems: First, the spec file doesn't use %defattr(-,root,root) to set file permissions, but instead relies on being run as root and using cp and worse, explicit install -m <blah> -o 0 -g 0 ... which will fail for anyone who can't chown things, ie anyone but root. Second, the spec file lists 'hdparm.lsm' as one of the %doc files. As of the tarball in the source RPM, it's instead 'hdparm-3.5.lsm'.
Fixed in hdparm-3.6-3.
