 It is not using %{_libdir} to define this macro and B) python _always_
 looks in /usr/lib/python2.7/site-packages, regardless of architecture.

 > Ok, you proposed solution for Ruby and for Python, but what about other
 noarch packages? I'd like to have some generic solution. Let say
 %{runtime_libdir}, alternatively %{runtime_arch} or whatever you call it
 which could be used universally across all languages etc.

 There can't be a '''runtime'''_libdir or '''runtime'''_arch that has any
 meaning in the buildsystem for noarch packages.  That is essentially what
 the existing %{_libdir} and %{_isa*} macros are and as stated, they are
 already either undefined or of no use for noarch packages.

 What you're really looking for is a %{buildtime_libdir} that defines the
 %{_libdir} on the buildsystem.  I'm not sure if this is a good idea.  It
 has a large potential for being used incorrectly and thus embedding the
 builder's %{_libdir} into something that gets installed.  OTOH, the
 potential already exists with per-language macros like %python_sitearch.
