--- Comment #2 from Andreas Bierfert andreas.bierfert@lowlatency.de --- Yes this is intentional. I'd prefer a setup like wine-gecko but this is what wine currently supports.
Here is the quote from: http://wiki.winehq.org/Mono "Unlike gecko, there is only one package containing the code for both x86 and x86_64, as most of the code does not depend on the architecture."
