This in nothing particular for FreeBSD...

Surely chmod doesn't want decimal 666? It wants octal
numbers! That's what the chmod codes are, an octal
representation for

rwxrwxrwx
110110110

In octal this is 666. To make python interpret it as
octal, write 0666. (Or write 438 if you want to confuse
people! ;)

os.chmod(fullpathtoscript+'/lists/'+mylist,0666)

(Who ever said zero means nothing?)

666 is octal 1232, and that's not what you want!

This is because umask = 022 I guess...
