Python 2.4 does not have python-config.
If you don't require Python tools, you can run:
  ./configure --disable-pythontools

Or you may avoid it:
  ./configure APPEND_INCLUDES=/usr/include/python2.4/

However, you will find an another issue:

checking for PyArg_ParseTuple in -l... no
configure: error: Unable to find a suitable python development library

I'm afraid I don't know how to avoid this issue.

I think we need handle this case with a fallback for pytyhon 2.3 and 2.4
which doesn't use python-config.

What did we used to do pre-autoconf?

Presumably this is a knock on effect from the previous failure and the
workaround you tried, which looks incomplete to me. I expect you need to
add -lpythonX.Y to some variable or other but the right solution is to
fix the python detection for the older python versions.

If I recall correctly we only checked for Python.h existence.

I've just posted a patch that hopefully covers all the supported
python versions, so we don't have to perform different checks
depending on the python versions, which is annoying.
