Comment(by ryandesign@…):

 As you see, on line 59 of your macports.conf, you've set "build_arch i386
 x86_64". This isn't a legal value for build_arch. It must be a single
 architecture only. Since you are on Snow Leopard, the default is "x86_64",
 and that is the value you should set build_arch to unless you have a
 specific reason not to.

 I've filed #22557 requesting MacPorts base detect an improper value in
 build_arch and alert the user, rather than trying to proceed and causing
 the more-confusing situation you encountered.
