That file doesn't exist in 2.4; the code it used to contain has been
folded into the core python24.dll (so _sre is builtin now, instead of
an extension module).

That shouldn't be possible, since _sre is a builtin now.

Don't know, can't guess.  Run Python 2.4 with the -v switch, then do

    import _sre

You should see something like

>>> import _sre
# C:\Python24\lib\encodings\cp437.pyc matches C:\Python24\lib\encodings\cp437.py
import encodings.cp437 # precompiled from C:\Python24\lib\encodings\cp437.pyc
import _sre # builtin
>>>

If you don't see something like that, it's A Clue.
