Packaging help needed: Prevent noarch package from requiring 32bit RPMs on a 64bit system

[Miro Hrončok]

Hi,
I am trying to package slic3r -> it is a perl noarch package, but it
requires a lot of arch specific perl modules.

The Requires section form spec file:

Requires:       perl(XML::SAX)
Requires:       perl(Growl::GNTP)
Requires:       perl(Net::DBus)
Requires:       perl(:MODULE_COMPAT_%(eval "`%{__perl} -V:version`";
echo $version))

https://github.com/hroncok/SPECS/blob/master/slic3r.spec

The rest of Requires are automatically added.

When I built the package and add it to the repository together with
required packages I made, it requires arch mishmash on a 64bit system:

 slic3r                         noarch   myrepo

Lines with myrepo are made by me, you can see specs here:
https://github.com/hroncok/SPECS/

As you can see, it installs 64bit required packages from officail
repositories, but it installs 32bit packages from mine (64bit packages
also exists, that's not the problem).

It installs slic3r, but it won't work, as it looks up its't arch
specific modules in 64bit directories.

If I manually run
yum install perl-Boost-Geometry-Utils perl-Math-Clipper
perl-Math-Factor-XS perl-Math-Geometry-Voronoi perl-Math-Prime-XS
slic3r

It works as expected (install 64bit packages).

What should I as a packager do, to avoid this situation?

Thank you very much.
