To install in 64-bit Kubuntu (or 64-bit Ubuntu, or 64-bit Ubuntu variants), you need the ia32 package installed. However, the ia32 package is missing a the libzip1 library. The fix, download the i386 libzip1 package from Debian Sid (
http://packages.debian.org/sid/libzip1 . You need to be sudo to do this - using your favorite archive tool (I like midnight commander), place libzip.so.1.0.0 into </usr/lib32>, & then create a symlink in </usr/lib32> called <libzip.so.1> and point it at </usr/lib32/libzip.so.1.0.0>. After that, it should work no problem (at least it worked for me in Kubuntu 10.10). Sure would be nicer to have a native 64 bit version though as no hacks like this would be needed.
