Seem I get no luck to build out the pykdump...
I git clone its tree from:
git://pykdump.git.sourceforge.net/gitroot/pykdump/pykdump
After this, I do the ./configure -c <crash build place>
and then make, the following error shows up:
Makefile:24: slocal.mk: No such file or directory
make: *** No rule to make target `slocal.mk'.  Stop.

Any idea?
