[ pokes around ]  Opcode is in the base perl package on RHEL6;
on Fedora 28, it's in perl-interpreter.  Either way, it's in the same
package as /usr/bin/perl, so ain't nobody not gonna have it.

Sounds good.  We can always tweak the list some more if the situation
changes, or if we hear from someone using a different distro that slices
things up yet differently.  But I don't feel a need to expend configure
cycles on purely hypothetical configurations.  I imagine that most
off-the-beaten-track cases would involve hand-built Perl installations,
and those will almost certainly have all of "Perl core".  So I think
as long as we cover what the major Linux distros are doing, that's
probably good enough.
