I don't see anything in that bug about CentOS-4.6, myself. I do see a bit about CentOS 3.9.

In any case, here is how CentOS4 and RHEL4 differ:

[root@zimbra-061 tmp]# cat /etc/redhat-release 
CentOS release 4.6 (Final)
[root@zimbra-061 tmp]# cat /tmp/system.pl 
#!/usr/bin/perl
use lib "/usr/lib/perl5/5.8.5";
use Scalar::Util qw (dualvar);
[root@zimbra-061 tmp]# perl /tmp/system.pl 
[root@zimbra-061 tmp]#

As you can see, on this stock CentOS 4.6 system, there is no error returned about Scalar::Util.

Now for RHEL4 Update 6:

[root@qa07 tmp]# cat /etc/redhat-release 
Red Hat Enterprise Linux ES release 4 (Nahant Update 6)
[root@qa07 tmp]# cat /tmp/system.pl 
#!/usr/bin/perl
use lib "/usr/lib/perl5/5.8.5";
use Scalar::Util qw (dualvar);
[root@qa07 tmp]# perl /tmp/system.pl 
 is only avaliable with the XS version at /tmp/system.pl line 3
BEGIN failed--compilation aborted at /tmp/system.pl line 3.
[root@qa07 tmp]#

So, decidedly not the same behavior.
