can't build port because thinks amd64 is i386?

[Gary Aitken]

Trying to build darktable on an amd64 machine:

uname -a
FreeBSD breakaway.dreamchaser.org 11.3-RELEASE-p6 FreeBSD 11.3-RELEASE-p6 #0: Tue Jan 28 09:37:40 UTC 2020     root at amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC  i386

/usr/ports/graphics/darktable # make
===>  darktable-2.4.2 is only for amd64, while you are running i386 (reason:
uses SSE instructions and 64-bit address space).

hints?

Thanks,

Gary
