Description of problem:

rpmbuild fails to detect requires or provides from perl module.

The root cause seems to be the /usr/lib/rpm/rpmdeps
On RHEL8 this tool shows

$ /usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --requires Logger.pm
perl(Sys::Syslog)
perl(strict)
perl(warnings)
$ /usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --provides Logger.pm
perl(UVic::Logger)

While on RHEL9

$ /usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --requires Logger.pm
$ /usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --provides Logger.pm

Version-Release number of selected component (if applicable):

$ rpm -qf /usr/lib/rpm/rpmdeps
rpm-build-4.16.1.3-19.el9_1.x86_64

How reproducible:

Take any perl module and run the rpmdeps commands on it.
I have attached the Logger.pm module I used in the description of my problem.

Steps to Reproduce:
1. Save he Logger.pm
2. Run the rpmdeps commands
/usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --requires Logger.pm
/usr/lib/rpm/rpmdeps --define="_use_internal_dependency_generator 1" --provides Logger.pm

Actual results:

null list

Expected results:

the requires list of:

perl(Sys::Syslog)
perl(strict)
perl(warnings)

and the provides list of:

perl(UVic::Logger)
