Installing Verilog::Netlist or Verilog::Parser (etc) from CPAN fail on my mac (Mojave 10.14, perl 5, version 26, subversion 3 (v5.26.3) built for darwin-thread-multi-2level
Other modules from CPAN do not fail in the same way, I think there is an old Mac workaround in the Verilog module Makefiles that is causing a problem.

The failing message is:
LD_RUN_PATH="/usr/lib" /usr/bin/clang -dynamiclib -lstdc++ -L/System/Library/Perl/5.26.3/darwin-thread-multi-2level/CORE -lperl -lgcc_eh -L/usr/local/lib VFileLine.o VParseLex.o VParse.o VParseBison.o VSymTable.o VAst.o -o ../blib/arch/auto/Verilog/Parser/Parser.bundle Parser_cleaned.o
-lstdc++ \

WSNYDER/Verilog-Perl-3.464.tar.gz
/usr/bin/make -- NOT OK

I went to ~/.cpan/build/Verilog-Perl-3.464-*/

There are these suspicious lines in the Makefile.PL which I commented out:

if ($^V eq '5.12.4') {
    $out .= sprintf("LDDLFLAGS = -dynamiclib -lstdc++ -L/System/Library/Perl/5.12/%s/CORE -lperl -L/usr/local/lib\n",$Config{archname});
} elsif ($^V eq '5.18.2') {
    $out .= sprintf("LDDLFLAGS = -dynamiclib -lstdc++ -L/System/Library/Perl/5.18/%s/CORE -lperl -L/usr/local/lib\n",$Config{archname});
} else {
    $out .= sprintf("LDDLFLAGS = -dynamiclib -lstdc++ -L/System/Library/Perl/%vd/%s/CORE -lperl -lgcc_eh -L/usr/local/lib\n",$^V,$Config{archname});
}

and elsewhere this reference to PERL_INC:
VFileLine.o: $(PPSRC)/VFileLine.cpp
$(CCCMD) $(CCCDLFLAGS) "-I$(PERL_INC)" $(PASTHRU_DEFINE) $(DEFINE) $<

When I commented out the lines with the sprintf and deleted the reference to PERL_INC (in multiple Makefile.PL files), I was able to pass make in the .cpan/build/Verilog* directory and install the modules manually. So I am not blocked, but future Mac OSX users will be.
