1. The spec file is included in the cpan2rpm-2.028.tar.gz, you can just untar 
it and extract out the cpan2rpm.spec.
2. Since the cpan2rpm uses a subroutine interpolate from POD::Text but it is 
not supported in the latest build of POD::Text. The fix is to replace the
'POD::Text' with 'POK::PlainText' in the two places of file 'cpan2rpm'.
3. Generate the cpan2rpm-2.028-1.noarch.rpm as general rpm package.
Add cpan2rpm, this is a rpm which can be used to create spec file from cpan tar.gz; Add perl-Net-DNS package, it is necessary for sles12 to support makedns for an issue in the version which shipped with sles12 Former-commit-id: 0475dcaa3d44ace25590909c5fde52292129cc89 2014-10-29 08:39:57 +00:00			`1.
