Writing portably for 1.5.1 using 1.5.2

Hello, people.
I'm using 1.5.2 on my development machines, but have to execute the scripts
on machines still having 1.5.1, from time to time. I notice that on 1.5.1,
I have to write:
if __name__ == '__main__':
apply(main, tuple(sys.argv[1:]))
instead of:
if __name__ == '__main__':
apply(main, sys.argv[1:])
There are some newer functions and modules, but it did not hurt me much
so far. Is there, by any chance, some guide about writing Python portably
between versions?
P.S. - I got a few unexpected bugs on a given system using 1.5.2, which
problems did not show on other 1.5.2 systems. Strange! For example,
exec 'recipes.append(%s())' % class_name
was always failing to resolve the name to a class. I'll postpone exploring
this problem. In the meantime, for this machine only, I reorganised all
the code so to not need `exec', and I feel better for stylistic reasons :-).
