It seems there was something wrong with the CentOS install. (Maybe
because it was slightly prior to the official release?)  When I copy
everything over to a fresh install, the provides and requires seem
correct. Happily, it also seems to have fixed the test failure in perl 5.20.

I now have contents of /etc/rpm/macros.perl520-config as:
%scl perl520
%__perl %_scl_root/usr/bin/perl
%__perl_requires /usr/lib/rpm/perl.perl520-req
%__perl_provides /usr/lib/rpm/perl.perl520-prov
%__perllib_requires /usr/lib/rpm/perl.perl520-req
%__perllib_provides /usr/lib/rpm/perl.perl520-prov

%scl_package_override() %{expand: \
%global __perl %_scl_root/usr/bin/perl \
%global __perl_requires /usr/lib/rpm/perl.perl520-req \
%global __perl_provides /usr/lib/rpm/perl.perl520-prov \
%global __perllib_requires /usr/lib/rpm/perl.perl520-req \
%global __perllib_provides /usr/lib/rpm/perl.perl520-prov \
}


As I understand it, I need the first set for building things in the
perl520 SCL, while the second set in the override will be used for other
SCLs that use the perl520 SCL?

Thank you for your help,
Malcolm
