Ah, I never think about using checkinstall - I haven't really used it in anger. For some reason, I thought you needed to structure your Makefile a certain way (using $DESTDIR or somesuch), but I seem to be confusing it with something else. Apparently, no change to the Makefile is required - it uses some kind of filesystem watcher to note which files are copied into place by 'make install'. heh, go figure! :-D

So, I think you only need to set the PREFIX when building (the default installation PREFIX is $HOME), or create a local.mk file to configure the build (I don't do that). The 'sparse' build does not make use of any 'auto-tools', so no configure script.

Ah, I think you will need to have pkg-config installed. I have never built sparse from a tar-ball - I assume it works! ;-)

So (just typing into my email client - not tested):

  $ wget http://www.kernel.org/pub/software/devel/sparse/dist/sparse-0.6.0.tar.gz
  $ tar xvf sparse-0.6.0.tar.gz
  $ cd sparse-0.6.0
  $ make PREFIX=/usr/local
  $ sudo checkinstall make PREFIX=/usr/local install

... should do it. (famous last words).
