I started playing with 10, and cannot get it to use the right version of perl. I'll only use the system version:

Hm, I don't think we've changed anything about that in v10.
But, here's the thing. The config.log reports 5.26 version:
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.

tldr: PG 10 compiles fine and works with perlbrew fine, I confused install paths.
I removed the plperl.so, and typed make:
gcc -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard -O2 -fPIC -DLINUX_OOM_SCORE_ADJ=0 -fPIC -shared -o plperl.so plperl.o SPI.o Util.o -L../../../src/port -L../../../src/common -Wl,--as-needed -Wl,-rpath,'/opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi/CORE',--enable-new-dtags -fstack-protector-strong -L/usr/local/lib -L/opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi/CORE -lperl -lpthread -lnsl -ldl -lm -lcrypt -lutil -lc
And in the src dir:
root@firefly:/tmp/SBo/postgresql-10rc1# ldd ./src/pl/plperl/plperl.so
libperl.so => /opt/perl5/perls/perl-5.26/lib/5.26.1/x86_64-linux-thread-multi/CORE/libperl.so (0x00007f33b9f87000)
I had 10beta1 installed to /usr/local/pg10.
The SlackBuild script I'm using installs to /usr/local/pg95 still. So I was compiling and installing 10rc1 into pg95.
Sorry for the noise (and thanks Tom).
