64 bit - Install wine1.6-amd64 from ubuntu-wine ppa asked for installing wine1.6-i386 as well

When installing wine1.6 and wine1.6-amd64 from ppa:ubuntu-wine on Kubuntu 12.10 (quantal), it always asked me for installing wine1.6-i386

However, how could I install wine1.6-i386 on a amd64 box? Therefore I need to download the package, extract it and change the dependency to remove wine1.6-i386 so that I can install this amd64 version of wine1.6.

wine1.5 has the same problem.

Any suggestions?

new information added:

Thanks for suggestions. However when I tried to install wine1.6-i386, it asked for a lot of other i386 packages like libgstreamer0.10-0:i386. I was not able to install it and didn't know how to solve such dependencies. Any help will be appreciated.
