Hm, I don't think we've changed anything about that in v10.

That's good, but what's probably missing is an "rpath" specification when
linking plperl.so. Did you build with --disable-rpath, perhaps? That's
the usual recommendation when building for Linux, but if you want to use
any non-default libraries, you can't do it.

Go into src/pl/plperl, remove and remake plperl.so, and see whether the
link command includes anything like

-Wl,-rpath,'/usr/lib64/perl5/CORE',--enable-new-dtags

(That's what I see when building with a stock Linux Perl configuration and
rpath enabled.) If there's no such switch, or if it doesn't point to
where the libperl.so that you want to use is, then there's your problem.
