To compile -lucre and s-lc, edit the Makefiles to reflect the locations
of the include files and library files for SSLeay and Berkeley db on your
system (if you don't have them, read the README file to find out where
to get them).  Edit the top-level Makefile to set the install locations.
Then do "make".  You should end up with "libucre.a" and "s-lc" in their
appropriate directories.  If that worked, "make install" will install
them, along with "lucre.h".  If you want to make a shared library instead,
you will need to edit the Makefile as appropriate for your system.
