It's true the build mechanisms of pykdump leave a lot to be desired.
You have to tell the thing where to find the python build tree, too,
because the process involves rolling up a largish subset of python
into the .so file.  After configuring there should be *three* .mk files.
I've attached a file showing how mine got set up for my platform
with my layout, meaning you won't be able to use it (directly), but
you'll see more-or-less what you need.  You'll find the pykdump guy
helpful 'cuz he helped me through exactly the same problems.  Weeks
ago now, so I've forgotten what exactly I had to do.... :)

Good luck.  Cheers - Bruce
