> XS modules need to be compiled when installed, using the same compiler as the Perl they are being installed to.

Can you please elaborate on this? I'm not familiar with XS, but a brief search turns up the "xsubpp" utility, which is apparently used to compile Perl XS code into C code. If I run xsubpp -v on each of the two machines, I receive the following output:

RHEL7: xsubpp version 2.21
RHEL8: xsubpp version 3.24

These xsubpp versions seem completely separate from any version of perl installed on the system. Are you saying that when an XS module such as List::Util is installed, whatever version of xsubpp happens to be installed on the system is used to compile the C code and from then on, only machines with that same version of xsubpp installed can use the module?
