RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Created attachment 532316 [details]
Patch to /usr/lib/rpm/perl.req to fix the issue

Description of problem:
/usr/lib/rpm/perl.req scans for the opening brace type on lines, but then only scans for closing curly braces ('}') instead of the proper losing brace type when that closing brace occures on a different line.  This means that any use/require statements that occur after the multi-line q{} statement but before the first closing curly brace in the file will be ignored.

Version-Release number of selected component (if applicable):
rpm-build-4.8.0-16.el6_1.1

How reproducible:
Run /usr/lib/rpm/perl.req on any perl module that uses something other than curly braces for a q{} across multiple lines when there are use/require statements after it but before a closing curly brace.

Steps to Reproduce:
1. /usr/lib/rpm/prel/req /usr/lib64/perl5/B.pm
2.
3.
  
Actual results:
perl(Exporter)
perl(XSLoader)

Expected results:
perl(Exporter)
perl(XSLoader)
perl(strict)

Additional info:
This appears to exist going back to at lest RHEL5, possibly earlier, and results in incomplete auto-generated Perl dependencies when building RPMs.
