This is not a good way to address this problem. What about 32-bit builds on
Snow Leopard -- for 32-bit CPUs, or for people selecting i386 build_arch in
macports.conf? What about 64-bit builds on Leopard? What about the OS that
comes after Snow Leopard? Instead, you should inspect the configure.build_arch
variable and enable 64-bit if the build_arch requests it. Note this is only
good for non-universal builds. For universal builds, you need to instead
inspect configure.universal_archs. Actually, you probably want to use the
muniversal portgroup so that you can pass --enable-apple-64bit to the 64-bit
builds and not pass it to the 32-bit builds. There are some example ports that
do this kind of thing.
