Comment(by 858wildcat@…):

 Sorry guys, I should have been more clear about what I'm *trying* to do.
 I've had macports installed for some time on a 64-bit capable machine.
 I'm attempting to rebuild the tree with universal binaries where possible.
 My attempt at doing that was to run "sudo port upgrade --enforce-variants
 installed +universal" where my settings in /etc/macports/macports.conf are
 as follows:

 universal_archs    x86_64 i386
 #build_archs    i386

 From the comments, it seems like build_archs should be x86_64 by default,
 but it is just commented out (so I assume it defaults to i386).

 Attached is the debug output from the build attempt.
