Thanks for investigating, hopefully fixed by:

Ok, confirmed by looking carefully at the build output here as well. The value of 'CPICFLAG' should probably be passed in to the 'gl' directory. But on my system, the build/install does not fail even with that option missing. So only seems to affect some, probably older, systems.

with pkg install -verbose parallel-3.1.3.tar.gz (created from current hg)

-fPIC seems to be missing here:

depbase=`echo perror.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        x86_64-pc-linux-gnu-gcc -DHAVE_CONFIG_H -I. -I..    -DEXTERNAL_BINARY -g -O2 -MT perror.o -MD -MP -MF $depbase.Tpo -c -o perror.o perror.c &&\
        mv -f $depbase.Tpo $depbase.Po

-fPIC is included in other compiles

CXXFLAGS="-O3 -Wno-expansion-to-defined " /opt/apps/shared/user/x86_64/bin/mkoctfile-5.2.1 --verbose -c fload.cc

Building the parallel package works for me with that configuration.

mkoctfile --version
mkoctfile, version 5.2.1

mkoctfile -p CXXPICFLAG

I can't reproduce this, and this isn't really a parallel package bug. Your Octave installation should be adding the -fPIC option (or system-dependent equivalent) automatically when it's needed. This isn't something packages need to worry about.

What does 'mkoctfile -p CXXPICFLAG' print? If it's not '-fPIC', then something may be wrong with your Octave install.

Building current mercurial 292:52f75987dd97 I get a linktime error message.

Manually adding -fPIC manually to CFLAGS/CXXFLAGS in config.status does allow the build to complete.
