Re: [Tutor] module paths
I copy/pasted your script and it ran fine on my end. Is it possible that
you've got more than one installation of python and the feedparser module is
installed somewhere other than for the python interpreter at
/usr/local/bin/python (since that's what your script references)? Perhaps
trying "python parse.py" will help since your code when you invoke the
python shell.

Re: [Tutor] confusing HTTP error while using urlopen
It looks like the site wants an Accept header. The following works:
import urllib2
url = 'http://www.anuntul.ro/'
headers = {'Accept': 'text/html'}
req = urllib2.Request(url=url, headers=headers)
rsp = urllib2.urlopen(req)
page = rsp.read()
print page

Do you have an __init__.py file in the tests and suites directories?
More on that here:
http://docs.python.org/tut/node8.html
"The __init__.py files are required to make Python treat the directories as
containing packages; this is done to prevent directories with a common name,
such as "string", from unintentionally hiding valid modules that occur later
on the module search path. In the simplest case, __init__.py can just be an
empty file, but it can also execute initialization code for the package or
set the __all__ variable, described later."

What was the error message? It should work fine:
In [25]: text = 'Bill Smith is nice'
In [26]: re.sub('Smith', '', text)
Out[26]: 'Bill is nice'
> If I have:
> text = "Jim likes a girl (Susan)"

You need to escape the parentheses because those are grouping
metacharacters in regular expressions:
In [27]: text = 'Jim likes a girl (Susan)'
In [28]: re.sub('\(Susan\)', '', text)
Out[28]: 'Jim likes a girl '

Calling urlopen with an https scheme should be sufficient as long as
python with SSL support is installed. I have the ActiveState Python
2.5.2 distribution on Windows XP and it seems to work fine:
In [3]: response = urllib2.urlopen('https://google.com')
In [4]: response = urllib2.urlopen('https://mail.google.com')
In [5]: html = response.read()

What URL are you trying this against? The URL in your code
"https://url.com"; doesn't seem to respond at all so I can't reproduce
your error. Have you tried against a well known HTTPS endpoint like
"https://mail.google.com";? What happens?
I'll try to guess anyway .. the Status Line in an HTTP response is the
first line that gives the response code, something like "HTTP/1.1 200
OK". Maybe your server is returning malformed headers?
