Comment 29 for bug 43324

The "64 bit package" I put at winehq is actually a 32 bit version (that only runs win32 and win16 apps), built to link against the 32 bit libraries on the 64 bit version of Ubuntu (which are in a different place than in the 32 bit version).

So, yes, it's what you want, and I'm not sure why it's not being built in Gutsy.
