What's going on here ? I'm confused.

[Dr. David Kirkby]

Hi,
        I've got three problems, which may or may not be related. I'm not sure 
if it's
an automake, autoconf or gtk problem. I've just downloaded and installed the
latest automake (1.6.1) and autoconf (2.53) which has not made any improvement
(if fact I got a bit further slightly older releases).

I've a farily simple program that needs the gtk library. I've copied a bit of
code from the configure.in of another package and are trying to use that. I
believe this defines a macro AM_PATH_GTK that searches for the library. I have 3
problems.

1) autoconf gives an error:
wren /export/home/davek/atlc % autoconf
configure.in:91: error: possibly undefined macro: AM_INIT_AUTOMAKE

2) automake gives an error

wren /export/home/davek/atlc % automake
configure.in:91: no proper implementation of AM_INIT_AUTOMAKE was found,
configure.in:91: probably because aclocal.m4 is missing...
configure.in:91: You should run aclocal to create this file, then
configure.in:91: run automake again.
src/gui/Makefile.am: required file `./depcomp' not found
/usr/local/stow/automake-1.6.1/share/automake-1.6/am/depend2.am: AMDEP does not
appear in AM_CONDITIONAL

3) Running aclocal gives an error about a missing library
wren /export/home/davek/atlc % aclocal
aclocal: configure.in: 126: macro `AM_PATH_GTK' not found in library

This last erorr is the one really bothering me. As far as I can tell, it is
defined in configure.in. 

Prior to updating automake and autoconf (originally 1.4 and 2.52), a configure
script was generated that run okay. Even the macro that is apparently undefined
ran okay, and worked as expected. However, the generated Makefile would always
fail to run with the "macro `AM_PATH_GTK' not found in library" message. 

Can anyone see what I'm doing wrong. I've attached the configure.in.
