The 2.6 installer image does not include 64-bit binaries.  As of this  
week the script that creates the installer can build an installer that  
does support 64-bit code as well, but that only works on Leopard  

I'm thinking about how to distribute binaries that support 64-bit code  
without unduly complicating the world. The easiest option for me would  
be to have two installers: one 32-bit only that supports OSX 10.3.9  
and later and a 4-way universal one that supports OSX Leopard and  
later.  It might be possible to have a single installer that supports  
64-bit code on Leopard but is usable on 10.3.9 as well, but I haven't  
checked yet how much that would complicate the build.
