Comment(by macports@…):

 Replying to [comment:6 michaelallenwarner@…]:
 > P.S. I'm not sure if this makes any difference, but since the whole
 32-bit vs. 64-bit thing seems to have come up in the OP by
 jmr at macports.org, I thought I'd mention that my Mac's hardware (MacBook
 4,1 from early 2008) is too old to run the operating system in 64 bits. So
 my OS Lion runs in 32 bits (though apps can run in 64 bits).
 >

 The ONLY Intel Mac that can't run 64bit code is the original Core Duo
 MacBook Pro. All subsequent machines are at least Core2 which can run
 64bit code. The CPU should be the only thing that determines what code you
 can run, and sure enough you can run plenty of 64bit apps. However, Apple
 installed a 32bit build of EFI on their Macs for several years and only
 switched to 64bit EFI relatively recently. That 64bit EFI is needed to run
 the kernel in 64bit mode as the bootloader lacks the ability to switch
 modes and launch a 64bit kernel from a 32bit environment. A little shim
 can be used during the boot to fix this. Before going to that trouble
 though, its worth testing what happens if you set the flag since even some
 machines with a 64bit EFI (like my 2008 MacBook Pro) still boot the kernel
 in 32bit mode by default. All that aside, it really doesn't matter if
 kernel is in 32 or 64bit mode to anything but a kext (drivers). All apps
 can execute in either regardless of which mode the kernel is in, so long
 as all dependent libraries are in the correct bitness for the app. AFAIK,
 macports will build x86_64 apps and libs as long as the CPU is capable,
 unless your macports.conf is changed or you set +universal. So, to make
 long story short, your machine isn't too old to run 64bit and most likely
 your entire macports collection is being built for 64bit, including gavl.
