Installation guide

[Andreas Ericsson]

This is because of a bug in the GD configure script. If you have libpng 
installed somewhere other than in /usr, it won't work.

To fix it, you can run the configure-script with your options and then
manually change the file config.h (somewhere in there, I don't remember 
where) and set the HAVE_PNG* and HAVE_JPG* (or JPEG) to be #define'd as 1.
The lines should be something like this;
#define HAVE_PNG_PNG_H 1
#define HAVE_PNG_LIB 1
#define HAVE_JPG_JPG_H 1
#define HAVE_JPG_LIB 1
Use your head about that though, cause I don't really remember the exact 
  definitions.

Then you have to modify the Makefile as well, and make sure CPPFLAGS 
includes the directory where you have the header files installed, and 
the LDFLAGS variable to include where you have your libraries installed 
and finally the LIBS statement must hold all libraries you want to link 
against.
On my system, that looks something like this when done;
CPPFLAGS=-I/usr/include -I/opt/include
LDFLAGS=-L/usr/lib -L/opt/lib
LIBS= -lpng -ljpeg -lz -lm -lfreetype -lpng12

Every -I<path> directive (in CPPFLAGS) tells the C PreProcessor (CPP) to 
look in those directories for the files it can't find (/usr/include is 
default, but added by the configure-script).
Every -l<short_lib_name> tells the linker (ld) in which libraries to 
look for symbols it needs to produce executables.
Every -L<path> (in LDFLAGS) tells the linker (ld) where it should expect 
to find the libraries mentioned in the -l<short_lib_name> statements.

That should do it, assuming you have the development environments for 
each respective package installed.
