I'd like to see comments added regarding the use of perl-bootstrap to 
show where the circular dependency is; these cycles may change over time 
as module implementations change, and some upstream module writers 
explicitly drop dependencies to avoid cycles, so it's useful to know why 
a BR was guarded by perl_bootstrap as it may be possible to remove it at 
a later date.

I've just added this in perl-Net-SSLeay for instance:

# Test::Kwalitee => Module::CPANTS::Analyze => Net::HTTP => 
IO::Socket::SSL => Net::SSLeay
%if 0%{!?perl_bootstrap:1}
BuildRequires:  perl(Test::Kwalitee)
%endif

Paul.
