Replying to myself, the file it reads is
`/usr/include/python2.7/pyconfig.h`  (for python2).

You can see the relevant code in the deeps of the initialization routines
of the python library, sysconfig.py:

    # load the installed pyconfig.h:
    config_h = get_config_h_filename()
    try:
        with open(config_h) as f:
            parse_config_h(f, vars)
    except IOError, e:
        msg = "invalid Python installation: unable to open %s" % config_h
        if hasattr(e, "strerror"):
            msg = msg + " (%s)" % e.strerror
        raise IOError(msg)

It seems to be used to discover the configuration of the current python
installation.

Just copying this file to your live media should be enough to make it
happy. Or alternatively, you might modify the sysconfig.py to read the file
from other place (`/usr/lib/python2.7` for example).
