I have a problem with the makefile (I don't know if this is specific to
this makefile or if it happens with the official version too; I haven't
tried).
  Since I noticed that libz and libpng are installed in this system, I decided
to perform dynamical linking of them to reduce the size of the executable.
  However, it seems impossible with the current makefile.
  The header files are located in the directory /share/local5/include/ and
the libraries are located at /share/local5/lib/
  However, the makefile seems to suppose that they are both located in the
same directory. Both LIBPNGINC and LIBPNGLIB use the same directory
(ie. PNGDIR). Setting them this way:

PNGDIR = /share/local5
LIBPNGINC = -I$(PNGDIR)/include
LIBPNGLIB = -L$(PNGDIR)/lib -lpng

doesn't help. The compilation fails with the message:

make: Fatal error: Don't know how to make target `/share/local5/png.h'

  I figured out how to do it:

PNGDIR = /share/local5/include
PNGLIBDIR = /share/local5/lib
LIBPNGINC = -I$(PNGDIR)
LIBPNGLIB = -L$(PNGLIBDIR) -lpng

  Now it works like a charm.
  I suggest a modification like this in the makefile (also with the libz).

I'll make note of that.  The long-term solution, of course, is a
configure script.
