The proper location for rpm macros files in rpm >= 4.11 is %{_rpmconfigdir}/macros.d, please move them there from /etc/rpm. If this package's specfile targets Fedora and EL >= 7 only, the location for macro files can be simply changed from /etc/rpm to %{_rpmconfigdir}/macros.d. If it is intended to work on EL 5 and/or 6 as well, you can define a macros dir for example as follows (all on one line) and install the macros to %{macrosdir}: %global macrosdir %(d=%{_rpmconfigdir}/macros.d; [ -d $d ] || d=%{_sysconfdir}/rpm; echo $d)
