Comment(by jameskyle@…):

 This is what I get if I don't specify the arch:

 {{{
 ld warning: -arch not specified
 }}}

 Though on my mac pro the resulting library is i386, I don't think this is
 the best option. My concern was how to appropriately determine the arch. I
 could do a shell out to determine the actual arch and assume all ppc are
 ppc (not ppc64) and all intel are i386 and not x86_64, but that feels
 kludgy and when Snow Leopard comes out would likely be incorrect.

 I'm open to suggestions.

 (also, on this most recent build I am still not getting the above ld
 errors)
