Yes, I know that there are ways around that limitation, but they are not an option for everyone who might be stuck with that OS.
I appreciate that position they find themselves in, but anyone who's chosen to tie a product to a vendor-supported release of Perl needs to go through that vendor for support, not volunteers. If you're sticking with a vendor such as CentOS or RH to ameliorate risk, then you ought to embrace their risk-management strategies rather than trying to work around them and taking on more risk.
(If you find their strategies onerous, you ought to reconsider whether that strategy really works for you, but even then, putting the burden of managing your own risk onto volunteers is not polite.)
