[opensuse-packaging] Python macros

Hello List, I'm just trying to put together a package containing python code. https://en.opensuse.org/openSUSE:Packaging_Python says I can use %{python_sitearch} (except for very old Suse releases), but when I build for tumbleweed, that just expands to the empty string. I have BuildRequires: python-rpm-macros and rpm --showrc spews out pages including -13: python_sitearch %{_python_sysconfig_path %python_flavor platlib} What am I missing? Thanks, A. -- Ansgar Esztermann Sysadmin http://www.mpibpc.mpg.de/grubmueller/esztermann
