No problem, Aap should work with Python 1.5.2.

You can ignore this error.  The aapre.py module is only used for Python
2.3.  This is a trick: we need the old pre.py module (it's twenty times
faster than the new one) but the Python 2.3 version gives a warning
message.  Thus I made a copy with the warning message removed.

It appears that installing continued after the error message.  Did you
try running Aap?  I would guess it just works.

Anyway, this change to Exec/main.aap should fix the problem:
