Yes, I have noticed this... (took me a while eh?) this is only on Tiger intel builds

You can add this in /etc/profile:
HOSTTYPE=i386
MACHTYPE=i386-apple-darwin8.0
export HOSTTYPE
export MACHTYPE

You can also go into bash with a hex editor and change the first two instances of powerpc, (the second set is the ppc portion of the universal binary) with the extra space leftover just pad it with zeros.

I often need to install OSs on Intel boxes, which frequently come without CDs or floppy these days. After some playing, here is how I use my PowerBook running OS X to do the job via pxeboot. The following example shows OpenBSD as the OS to install on the Intel box.

On a Mac Pro:
uname -a
Darwin computer.local 8.9.2 Darwin Kernel Version 8.9.2: Thu Feb 22 18:08:23 PST 2007; root:xnu-792.19.2~1/RELEASE_I386 i386 i386

machine
i486

set | grep TYPE
HOSTTYPE=powerpc
MACHTYPE=powerpc-apple-darwin8.0
OSTYPE=darwin8.0

So nowhere is there any mention of x86-64. that really throws a spanner in the works for porting 64b apps.

Still broken as of Oct. 20th, 2006. This is a Mac Pro running 10.4.8.

$ uname -a
Darwin delices 8.8.1 Darwin Kernel Version 8.8.1: Mon Sep 25 19:42:00 PDT 2006; root:xnu-792.13.8.obj~1/RELEASE_I386 i386 i386
$ set | grep -i type
HOSTTYPE=powerpc
MACHTYPE=powerpc-apple-darwin8.0
OSTYPE=darwin8.0

I'm more annoyed by the i386 kernel, personally.
