perl-ExtUtils-Embed and perl(ExtUtils::Embed)
are not the same thing:

* perl-ExtUtils-Embed refers to a package named "perl-ExtUtils-Embed"

* perl(ExtUtils::Embed) refers to the perl module providing 
"ExtUtils::Embed".

As perl modules may move between packages at any time, there is no 
strict connection between a perl module and a package (which happens to 
temporarily provide a module).

That said, it's Fedora perl-packaging convention not use perl packages 
but to use perl module names for BuildRequires/Requires/Provides.
Furthermore, rpm automatically adds many (theoretically all) 
Provides/Requires based on perl modules.
