[Image-SIG] undefined symbol: Py_InitModule4: more information

I have 3 copies of Python on my system: the Python 1.5 that
RedHat uses in the /usr tree, Python 2.1, also in the /usr tree,
and Python 2.1 compiled with the "--with-pydebug" switch. This
latter copy is in the /usr/local directory tree. If I type
"python", I get /usr/bin/python because of a "ln -s".
I am trying to install PIL with the Python debugging stuff
included. What am I doing wrong?
The make process in libImaging does not appear to depend on
Python in any way.
The first try at "make -f Makefile.pre.in boot" failed because it
couldn't find tcl8.0. A change in Setup to "8.3" fixed that.
I made the following assumption: The default settings for
installing PIL assume Python is in the /usr/local/lib tree.
Therefore the "--with-pydebug" version of the include files, etc.
will be found. A second attempt at "make -f Makefile.pre.in boot"
and "make" worked. I did "PYTHONPATH=.:./PIL ; export PYTHONPATH"
and then "/usr/local/bin/python2.1". An attempt to "import
_imaging" gave an error message. Here is the session:
Python 2.1 (#8, Jun 26 2001, 16:22:28)

If I modify /usr/local/src/Imaging-1.1.2/Makefile.pre.in to say
# Installed python binary (used only by boot target)
then I get the error:
make: Entering directory `/usr/local/src/Imaging-1.1.2'
make: *** No rule to make target `Print'. Stop.
make: Leaving directory `/usr/local/src/Imaging-1.1.2'
