Issue
I am trying to bundle a bunch of Perl modules in RPM packages for easy deployments. I've tried a lot of tools but settled on fpm (https://github.com/jordansissel/fpm).
So I've managed to manually build and install each RPM for each of the required Perl modules. I'm not sure this is correct. But I don't have a lot of experience with RPM packages. But as far as I can tell, this is the correct behavior. Each RPM package contains all required dependencies for the corresponding Perl module.
The problem is I get some conflicts when I try to use the resulting bundle to install my modules.
sudo yum --disablerepo=* localinstall *.rpm
And when it tries to install:

I've spent days trying to debug the issue but I can't seem to figure it out. All I did was install perl using yum since that was a prerequisite. I expected my local install would work.
Solution
The error message seems clear: you can't have two packages providing the same file.
For the errors around Moose.so, you would probably want to move the shared library into a separate package and make it a dependency of all the modules that require it.
For the errors around HTML-HeadParser, I think you would simply have a HTML-Parser package and that make things like HTML-HeadParser and HTML-Entitities depend on it.
Maybe take some time and look at how the existing Perl modules are packaged? For example, look at:
- perl-HTML-Parser
- perl-HTML-Entities-Interpolate
- perl-Moose and all the other
perl-Moose-*andperl-MooseX-*packages in the same repository.
