Just a couple of guesses,

Have you got the kernel headers for the kernel installed? You should be able to by apt-get install kernel-headers-2.6.11. I'm not sure that you can get them yet from the stock depositories.

You might need to get or invoke different gcc libraries, I believe there is a tag that you can use to do that but I'm not that up on it. If you can find the version of gcc that the program expects, I think you can pass it to your make command.

Google it up or search the forums with this suggestion, hopefully someone with more experience will chime in with more.
