Why not modify the script so that instead of having to substitute
@@PERL_REQ@@, the necessary value is passed as a parameter to it?

So the spec looks like this:

...
Source1:        filter-requires.sh
...
%prep
%setup -q -n Kwiki-Raw-%{version}
%global real_perl_requires %{__perl_requires}
%define __perl_requires %{SOURCE1} %{real_perl_requires}

There's no need to delete anything extra in %clean

The filter-requires.sh looks like this:

#!/bin/sh
PERL_REQ="$1"; shift
"${PERL_REQ}" "$@" | /bin/grep -Fvx '
perl(mixin)
'

Where multiple dependencies need to be filtered, add them one per line
where perl(mixin) is.

The only "unusual" requirement here is that the filter-requires.sh needs
to be executable in the SRPM, thus avoiding the need to chmod it.
