feedparser - various errors

I need feedparser (se http://www.feedparser.org) for a project, and want to keep third party modules in a separate folder. I did this by adding a folder to my python path, and putting relevant modules there, among them feedparser.

This first attempt to import feedparser resulted in

>>> import feedparserTraceback (most recent call last):  File "", line 1, in   File "/home/users/me/modules/feedparser.py", line 1    ed socket timeout; added support for chardet library            ^SyntaxError: invalid syntax

I found the text "socket timeout; added..." in the comments at the bottom of the file, removed these comments, and tried again:

>>> import feedparserTraceback (most recent call last):    File "", line 1, in     File "/home/users/me/modules/feedparser.py", line 1    = [(key, value) for key, value in attrs if key in self.acceptable_attributes]    ^IndentationError: unexpected indent

Ok, so some indent error. I made sure the indent in the function in question where ok (moved some line breaks down to no-indent). And tried again:

>>> import feedparserTraceback (most recent call last):  File "", line 1, in   File "/home/users/me/modules/feedparser.py", line 1    , value) for key, value in attrs if key in self.acceptable_attributes]    ^SyntaxError: invalid syntax

As much I google, I cannot find anything wrong with the syntax:

def unknown_starttag(self, tag, attrs):    if not tag in self.acceptable_elements:        if tag in self.unacceptable_elements_with_end_tag:            self.unacceptablestack += 1        return    attrs = self.normalize_attrs(attrs)    attrs = [(key, value) for key, value in attrs if key in self.acceptable_attributes]    _BaseHTMLProcessor.unknown_starttag(self, tag, attrs)

Now what?Is my approach all wrong? Why do I keep producing these errors in a module that seems so well tested and trusted?
