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.solibperl.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).
