Rebuild won't help. The problem is that licensecheck somehow re::engine::RE2 without declaring the RPM dependency on it. I will look where the use is.

This is a bug in Regexp/Pattern/License.pm:

my $CAN_RE2;
                
BEGIN {             
    eval { require re::engine::RE2 };
    $CAN_RE2 = $@ ? '' : 1;
}                   
[...]
            if ( $args{engine} eq 'RE2' ) {
                unless ($CAN_RE2) {
                    die
                        'cannot use regexp engine "RE2": Module "re::engine::RE2" is not installed';
                }
                    
                BEGIN {
→                   re::engine::RE2->import(
                        -strict  => 1,
                        -max_mem => 8 << 21,
                    );
                }
                return qr/$pat/;
            }

It optimizes re::engine::RE2 initialization with a BEGIN block, but the initialization does not take $CAN_RE2 result into account. Obviously the dependency on re::engine::RE2 was intended to be optional.

A fix is available upstream at <https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=1078071;filename=only-import-reenginere2-when-available.patch;msg=10>.

This bug is not related to re2 update. It's an old bug which became visible with perl-5.40.0.

A reproducer:

$ perl -e 'use Regexp::Pattern::License;'
Attempt to call undefined import method with arguments ("-strict" ...) via package "re::engine::RE2" (Perhaps you forgot to load the package?) at /usr/share/perl5/vendor_perl/Regexp/Pattern/License.pm line 15550.

Thanks for the heads up!

In parallel to what Petr is doing, I was able to rebuild that package on Fedora Rawhide (F42), and the Fedora update is now available: https://bodhi.fedoraproject.org/updates/FEDORA-2024-05f8d22295

At this time, I was not able to create an update for Fedora 41 (IIUC, it is being branched/composed/synchronized right now; we may have to trigger a build on F41 specifically once that option will become available).

I'm finished with the analysis. It's up to regular maintainer to apply the fix.

* Fedora update for Rawhide (F42): https://bodhi.fedoraproject.org/updates/FEDORA-2024-05f8d22295

It should be possible to build for F41 already - branching is already over AFAIK.

Indeed, I was able to build for Fedora 41: https://koji.fedoraproject.org/koji/buildinfo?buildID=2530324
But when trying to create a Fedora update, I get the following error:
> Builds : Cannot manually create updates for a Release which is not composed by Bodhi. Read the 'Automatic updates' page in Bodhi docs about this error.

Bodhi updates are created automatically for F41 the same way as for F42. See <https://bodhi.fedoraproject.org/updates/FEDORA-2024-1a8b91da1b>.

However, the builds are pointless because a simple rebuild won't fix the reported issue.

My bad: the update was eventually created automatically by Bodhi (I checked for an update in Bodhi too early, and it was not there yet): https://bodhi.fedoraproject.org/updates/FEDORA-2024-1a8b91da1b

Focusing on the rebuild, I overlooked your messages stating that RE2 was not the cause of the reported issue. I get it now. Even though pointless, the rebuild will not harm, hopefully :)
