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 -=
