I would need to see the config.log file to determine why this test
fails. I can't do anything without it.

GD often requires PNG, so this may just be a consequence of the PNG
failure.

Odd. This check (AC_CHECK_HEADERS) involves attempting to pre-process
(via e.g. "cpp", "gcc -E" or similar) the following test program:

	#line 5436 "configure"
	#include "confdefs.h"
	#include <tk.h>

If the check fails, but tk.h is present, this implies that
pre-processing tk.h fails, e.g. because one of the headers which tk.h
includes can't be found.

My suspicion is that the X headers can't be found. I'll look into
adding the appropriate -I switch(es) automatically (via X_CFLAGS). If
I'm correct, you should be able to work around the problem using e.g. 

	--with-tcltk-includes=/usr/X11R6/include

Note: this option accepts a space-separated list of directories, e.g.

	--with-tcltk-includes='/usr/local/include /usr/X11R6/include'

This is an artifact of the tk.h test failing.

Possibly related to X libraries, although I would need to see
config.log to be sure.

I don't think that anything uses them at present.
