The curses module and licensing

I think I have accidentially not sent this to the python list:

Thanks for your answer. I guess you're right. It's just, that I
never really worked for a project where I got into license
issues. (At least I think so.) And I am not really used to it.
The FAQ states:

"...to deal in the Software without restriction..."
"...distribute, distribute with modifications, sublicense..."
Sounds good. Ok, but I have to include this into all "copies or
substantial portions of the Software" . Ok, thats a bit vague.
And if I include this notice into my files: It sounds a bit, as
if this would be then a copyright for them.
Substantial portions are, I guess, the libraries themselves.
Which are other substantial portions? Those files which extend
the libraries maybe? I looked into the files of my
/usr/lib/python2.7/curses directory. None of them had this text
portion from above included. On the other hand the FAQ also
states that the Free Software Foundation, who got hold of the
copyright, had promised to use the above distribution terms only
for 5 years, which was in 1998, so it might not be relevant at
all. Well ok. I guess I can just leave my files, as they are,
since they are no real extensions of the library. But I am not
completely sure. If anyone has a better idea: Just let me know
