Since I haven't managed to find a command line pastebin script whose based on the new APIs I wrote one.
You can find it on my bitbucket.
$ pastebin.py -f python -e 10M -p 1 -t MyPaste < whatever

Here are some options:
-f defines data format (php, python, etc) -e the expiry time (10M, 1G, 1D, N) -p the privacy (1 is private, 0 is public) -t the title of the paste

Feel free to fork/edit/whatever it.
