Perl dependency error

I have an RPM package "mypackage" which depends upon /bin/perl, but
will not install, allegedly because it cannot see the perl package in
the upstream CentOS7 repository.

I've included the output from "yum install mypackage" below.

Strangely yum notices the dependency upon /bin/perl and announces:
---> Package perl.x86_64 4:5.16.3-291.el7 will be installed

But then dies with the error:
Error: Package: mypackage-0.0.6-1.mydist.noarch
(/mypackage-0.0.6-1.mydist.noarch)
           Requires: /bin/perl

Attempting to install both perl and mypackage in the same yum
installation command also fails.

I can manually install perl.x86_64 4:5.16.3-291.el7 before installing
mypackage, and will then a subsequent installation of mypackage will
succeed.  After manually installing perl, my RPM DB does associate
/bin/perl with the perl package:

$ rpm -q --whatprovides /bin/perl
perl-5.16.3-291.el7.x86_64

Interestingly, I notice the CentOS7 perl package is one of the few
packages with an epoch defined.

Question: Why does installation of mypackage not also pull in the perl
dependency?

thanks,
Jeff

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
