ical patch installation error


I was trying to apply the ical patch located here: http://www.projectpier.org/node/491

with the patch < file.patch command and I received the following errors.

What am I missing? It seems pretty simple.

patching file FeedController.class.php
Hunk #1 FAILED at 115.
Hunk #2 FAILED at 154.
Hunk #3 succeeded at 238 (offset 43 lines).
Hunk #4 succeeded at 265 (offset 13 lines).
2 out of 4 hunks FAILED -- saving rejects to file FeedController.class.php.rej

You do not need this in 0.8.6, it is already integrated.

Any other version, sorry.
