See http://docs.python.org/lib/built-in-funcs.html which shows the
current built-ins for Python. It also shows an equivalent function for
all() that should work in 2.4.

You can do a check at the beginning of your file by importing the sys
module. Something like this:

<code>
# untested
import sys
version = sys.version.split(' ')[0]

if '2.5' not in version:
   # use custom all() script

</code>
