gprolog tries to compile for a 486.

[stevenshack@…]

When I try to install gprolog with "port install gprolog" it tries to compile for a 486.

---> Building gprolog Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gprolog/work/gprolog-1.3.1/src" && /usr/bin/make -j2 all " returned error 2 Command output: (cd EnginePl; /usr/bin/make config) /usr/bin/gcc-4.2 -march=i486 -O3 -fomit-frame-pointer -o pl_config pl_config.c pl_config.c:1: error: CPU you selected does not support x86-64 instruction set pl_config.c:1: error: CPU you selected does not support x86-64 instruction set make[1]: * [pl_config] Error 1 make: * [all] Error 2
