Can't figure out how to add a file to this @#$%*@#%$ bug

Here's a checker to compare urljoin from urlparse and uriparse

import urllib2
import urlparse
import uriparse
import BeautifulSoup

for url in (
    "http://python.org/",
    "http://www.perl.org/",
##    "http://aspn.activestate.com/ASPN/Cookbook/Python", #
they have \n in urls!

    ):
    print "Processing", url
    f = urllib2.urlopen(url)
    soup = BeautifulSoup.BeautifulSoup(f)

    rel_url_list = []
    for a in soup.findAll("a", href=True):
        rel_url_list.append(a["href"])
    for img in soup.findAll("img", src=True):
        rel_url_list.append(img["src"])

    for rel_url in rel_url_list:
        rel_url = rel_url.strip()
        url_joined = urlparse.urljoin(url, rel_url)
        uri_joined = uriparse.urljoin(url, rel_url)
        if url_joined != uri_joined:
            # urijoin can add an extra '/'
##            if url_joined == uri_joined+"/":
##                continue
##            if url_joined.replace("//", "/") ==
uri_joined.replace("//", "/"):
##                continue
##            # 'http://cnn.com/' u'/cnnsi/scorecard/?cnn=yes'
##            # url_joined ==

##            # uri_joined ==

##            if url_joined.replace("/?", "?") == uri_joined:
##                continue
            
            print repr(url), repr(rel_url)
            print "  ", repr(url_joined), "!=", repr(uri_joined)
