If you have debian system with all neccessary packages installed, type
dpkg-buildpackage (or dpkg-buildpackage -rfakeroot) in the package's
directory, then type
dpkg -i ../gtkctrlaltdel*deb

Else:

1) look at Makefile 

2) type make
   This should produce the executable.

3) become root

4) type make install

5) if you are brave enough, make gtkctrlaltdel setuid root :-)
