You are talking about compiling the package from source, where the OP might have a problem. I thought he was talking about the Windows binaries, which should work on a 64-bit system. (the last line of the original message: "*yes, yes, I know. download the source and compile it myself") The only problem I can see is that 32-bit programs can't access 64-bit dlls, so the OP might have to install the 32-bit version of Python for it to work.
