Well, the problem I had when I last tried 64bits wasn't the  
compilation, but at runtime.  Some of the vector modules would crash,  
and the closest I could track it down was (I think) somewhere in the  
diglib...  And as I write this it connects in my brain that your  
compilation error is in diglib...

...

It looks like the error was really back in those 4 libraries - they  
didn't compile with x86_64 for some reason.

Try make clean in those folders and make again, and check that -arch  
x86_64 is in all compile commands and the final link command.

I'll give it a try myself...
