Unable to find the wrapper "feed" RSSParser Library

[eluser]nnash[/eluser]
If I change the wrapper to http:// these messages are produced:

Code:

Severity: Notice

Message: Undefined variable: cache_dir

Filename: libraries/RSSParser.php

Line Number: 114

Edit:
The undefined cache_dir variable on line 114 of the RSSParser library that CodeIgniter published on their wiki is simple a log_message() that can be commented out.
End Edit

Now it is saying there is compile error with the RSSParser class, since I did not write it I don't really know what the error could be since I just copy and pasted it from the CI wiki, which you can find here http://codeigniter.com/wiki/RSSParser/.

Code:

Severity: Notice

Message: Undefined property: CI_Loader::$rssparser

Filename: theme/content.php

Line Number: 24

The second error message is in reference to the fifth line in the second code block on my first post.
