The inconsistency is in the naming of projects and rpm packages. A separate namespace for Python packages like with Perl modules should. For example, the yum package would provider python(yum), python(repomd), and python(rpmUtils). Instead of depending on yum, yum-utils could depend on python(yum). Perl and Ruby work similarly. Perl, at least for newer packages, names the tarballs after the modules contained inside. Some of the older modules don't follow the naming scheme. Which is why there is a separate namespace for the modules. For example, perl(LWP) is provided by perl-libwww-perl with the file /usr/lib/perl5/vendor_perl/5.8.6/LWP.pm. - Ian -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
