 It appears gtk2 uses "`sysctl hw.cpu64bit_capable`" in its universal
 variant, but this doesn't exist on Tiger so the port fails with this
 peculiar error message:

 Here's what it says if I run it manually:

 {{{
 $ sysctl hw.cpu64bit_capable
 second level name cpu64bit_capable in hw.cpu64bit_capable is invalid
 }}}

 Here's all the properties that are available on my 64-bit capable MacBook
 Pro:

 Perhaps we could check "hw.optional.x86_64" instead? That sounds
 promising, and appears to still exist on Snow Leopard. Or we could use
 hw.cpu64bit_capable on Leopard and up and just special-case Tiger. I don't
 know what the PowerPC equivalent of hw.optional.x86_64 is though because I
 don't have a Mac with a G5 processor to check on.
