[Message part 1 (text/plain, inline)]

Package: pari
Version: 2.3.4
Tags: patch

FreeBSD refers to the x86_64 architecture under its original name of
'amd64'.  Since pari is only looking for x86_64, it fails to correctly
recognize that it needs to add '-fPIC' to the shared library compilation.

This is reported during ./Configure:
        Warning ! architecture amd64 not tested

When (eg) "make bench" is then attempted, it fails with:

/usr/bin/gcc  -o libpari.so.2.3.4 -shared  -O3 -Wall -fno-strict-aliasing -fomit-frame-pointer  -Wl,-shared,-soname=libpari.so.2 mp.o mpinl.o Flx.o Qfb.o RgX.o alglin1.o alglin2.o arith1.o arith2.o base1.o base2.o base3.o base4.o base5.o bibli1.o bibli2.o buch1.o buch2.o buch3.o buch4.o galconj.o gen1.o gen2.o gen3.o ifactor1.o perm.o polarit1.o polarit2.o polarit3.o rootpol.o subcyclo.o subgroup.o trans1.o trans2.o trans3.o anal.o compat.o default.o errmsg.o es.o init.o intnum.o members.o sumiter.o aprcl.o elldata.o elliptic.o galois.o groupid.o kummer.o mpqs.o nffactor.o part.o stark.o subfield.o thue.o -lc -lm 
/usr/bin/ld: mp.o: relocation R_X86_64_32S can not be used when making a shared object; recompile with -fPIC
mp.o: could not read symbols: Bad value
*** Error code 1
