Tim,

I traced the build failure to a Debian patch from Debian bug report 357775. The specific patch is 11_fix_get_libdir_name.diff, which can be viewed here, about midpoint in the page:

http://lists.alioth.debian.org/pipermail/pkg-kde-commits/2006-June/003702.html

I reversed the patch and then was able to build on 64-bit. Ignoring obvious file size differences, my 64-bit package looks exactly the same as my 32-bit package.

In my patch I added some informational text to help debugging because the specific build failure message appears in three different locations. Here is my proposed patch:

Do you want me to push this patch to GIT or do you want to first run a Debian/Ubuntu test build?
