With a lot of help I got kcheckers working:

kckeckers is in QT where I changed the title to make it show up.
I have a separate Debian ARM partition that I chroot into using qemu. I can apt-get what I need easily this way. twobob and many others do the compiling other ways - twobob has an image to mount that you can mount on the kindle and do the work from there.
You should be able to search many examples of how to compile.
