I bet your Ubuntu installation is 32bit, too. You need a 64bit
installation of Ubuntu in order to run a 64bit version of Python. By
default Python is compiled in the same flavor as the OS. What does
"uname -m" show? It should print "x86_64" for a 64bit version of Linux.
--enable-universalsdk and --with-universal-archs have no function on
Linux. They are Mac OS X only options.
