in order to be able to use the same spec files both on SLES8 and SL 9.0,
the macro %perl_process_packlist must be made available on SLES8:

- copy the macro definition of %perl_process_packlist from a SL 9.0
  file /usr/lib/rpm/suse_macros to the new file /usr/lib/rpm/sc_macros_sles8
- %perl_process_packlist depends on the macros %perl_vendorlib and
  %perl_vendorarch which are missing in SLES8. Copy them from a SL 9.0
  file /usr/lib/rpm/macros to /usr/lib/rpm/sc_macros_sles8 on SLES8
- finally add /usr/lib/rpm/sc_macros_sles8 to the definition of macrofiles
  (search for the line beginning with "macrofiles:")
  in /usr/lib/rpm/rpmrc on SLES8

But this does not help us if we are using a chrooted build environment,
because then /usr/lib/rpm/ all comes from the rpm rpm-package.
Better approach is to create spec-files which determine the current
OS and do the right things based on that. The macro %suse_version can
be used for that. There exist macros called %ul_version and %sles_version
but if we use them, we probably run into problems on norma SL systems.
