Well it *is* the 64bit install of Mma. And yes, the installer did detect the 
arch properly and installed the 64bit version. But for some reason it also 
required the above 32bit library as well. It was a fresh install of both F12 
and Mma.

I haven't looked into it really, but my guess is that there is a bug in either 
Mma 6 or its installer script, so it requires one 32bit piece. Or maybe it was 
a genuine requirement, some piece of code there might have still relied on 
32bit stuff (the front end, some library, package, or whatever...). Apparently 
version 7 doesn't have this problem anymore (but I didn't check this yet).

Best, :-)
