cpan2rpm could implement a workaround, adding extra Provides: tags
just the way I did by hand, but it still seems to me that the root
cause is /usr/lib/rpm/perl.prov, which is part of RPM, so I thought
I'd start here. I'm relatively new to package building so I could be
wrong, but that's how it looks.

But good to know.

I've been using cpan2rpm a fair amount, and sometimes the rpm files
it produces refuse to install because of dependency issues. After
investigating, I think it's because of a problem with rpm's
automatic dependency generators for Perl.
The problem occurs when a Perl .pm file in a CPAN module has a
'use' statement that corresponds to a .pm file also in the module,
but that second file's 'package' statement doesn't match the
filename. This is legal Perl. rpmbuild will generate a requires for
the filename and a provides for the package. Since these don't
match, the RPM won't install because it appears to require things
that don't exist.
For example, take CPAN module VCS::LibCVS, whose RPM failed to
install with several requirements not met.
In one of its files, VCS/LibCVS/Client.pm, it has a use statement
use VCS::LibCVS::Client::Request::Requests;
which causes it to load VCS/LibCVS/Client/Request/Requests.pm,
which is also part of VCS::LibCVS. But Requests.pm has no package
statement for VCS::LibCVS::Client::Request::Requests. It defines
many other packages, but not that one. This is OK, because none of
the LibCVS code ever tries to create an object by that name. So
the code is fine.
But perl.req scans for 'use' statements, and generates a
requirement for perl(VCS::LibCVS::Client::Request::Requests),
while perl.prov scans for 'package' statements, so it never says
that this module provides a matching package. Result: when I try
to install the package, rpm says that it is missing
perl(VCS::LibCVS::Client::Request::Requests). This happens for
several other requirements as well.
I can get around this by adding Provides: tags for the "missing"
packages, but it seems to me that perl.prov ought not to scan for
package statements. It should just use the things that 'use'
statements actually care about - the filenames themselves.
