Hmpf. Reminds me of the odd situation of pygtk in Debian. Currently 
the gtk 1.2 bindings are still the default. Probably that should be
fixed.

This throws up the question if you need the gtk 1.2 or 2.0 bindings
for that tool...

Argh. Whoever wrote that script should be larted. Because the error
message does not match reality. In fact, configure.in does not ask the
python interpreter to find gtk.py:

    dnl Check if python bindings for gtk are installed

    AC_CHECK_PROG(have_pygtk, gtk.py, yes, no, $PYTHON_SITE_DIR)

    if test "x$have_pygtk" != xyes
    then
       AC_MSG_ERROR([
    **** The python interpreter can't find the python bindings for gtk.])
    fi

Where does that call python? In fact, even $PYTHON_SITE_DIR does not
make much sense. In realitas python searches in a number of paths which 
can be adjusted by throwing a file with extension .pth in there, like
python-gtk does:

[EMAIL PROTECTED]:~$ dpkg -L python-gtk|grep pygtk.pth
/usr/lib/python2.2/site-packages/pygtk.pth
[EMAIL PROTECTED]:~$ cat /usr/lib/python2.2/site-packages/pygtk.pth
gtk-1.2

This results in the following search list in python:

[EMAIL PROTECTED]:~$ python -c "import sys; print sys.path"
['', '/usr/lib/python2.2', '/usr/lib/python2.2/plat-linux2',
'/usr/lib/python2.2/lib-tk', '/usr/lib/python2.2/lib-dynload',
'/usr/local/lib/python2.2/site-packages', '/usr/local/lib/site-python',
'/usr/lib/python2.2/site-packages',
'/usr/lib/python2.2/site-packages/Numeric',
'/usr/lib/python2.2/site-packages/PIL',
'/usr/lib/python2.2/site-packages/gtk-1.2', '/usr/lib/site-python']

This is what the script should check for. Or, just use python to figure
out the path:

code="
import sys
try:
  import gtk
except ImportError:
  sys.exit(1)
except:
  sys.exit(0)
sys.exit(0)"
if $PYTHON -c "$code"; then
  AC_MSG_RESULT(yes)
else
  AC_MSG_ERROR("no gtk.py found")
fi

Something along the lines - did not write autoconf for a while...
