It seems like it can't handle x64 bit libraries, even though I'm on an x64 bit system.

The problem was:
ia32-sun-java6-bin

Even though I had the x64 version of java installed too, this 32 bit one was the default one in use, so when I tried to run the x64 version of sikuli, the 32bit java didn't like the 64bit libs, and when I tried to run the 32bit sikuli, then the systems 64bit opencv libs didn't work.

removing the ia32-sun-java6-bin package fixed it, but I don't recall if that was installed for a specific reason...

This looks like a bug (or misunderstanding) with the packaging of java in ubuntu or something not necessarily related to sikuli
