First, remove /usr/local/bin/psql and anything else in /usr/local/{bin,etc,include,lib,libexec,man,sbin,share,var}; these things interfere with software built using MacPorts.

Second, indeed it sounds like your lipo doesn't understand the x86_64 architecture. It sounds a lot like this ticket

http://trac.macports.org/ticket/24825

in which the end result was that the user had apparently somehow replaced /usr/bin/lipo with an older version. Please check whether that's the case for you as well: run

/usr/bin/lipo -info /usr/lib/libz.dylib

This should say that the file contains the architectures "x86_64 i386 ppc7400". But if it still mentions "cputype 16777223 cpusubtype 3" instead of "x86_64", then please replace /usr/bin/lipo with a good copy from your backups or from your Mac OS X installation media.
