Please provide any additional information below.

in my system , which connects to the internet via a proxy , this code works

proxy_support = urllib2.ProxyHandler({'http': 
'http://168.219.61.250:8080/'})
opener = urllib2.build_opener(proxy_support)
urllib2.install_opener(opener)
response = urllib2.urlopen('http://python.org/')
html = response.read()
print html

Hello there

i tried some quick hacking 

if  i add the following code to http_Request, everything works ok

    proxy_support = urllib2.ProxyHandler( {'http': 'http://168.219.61.250:8080/'} /* 
my proxy */ )
    opener = urllib2.build_opener(proxy_support)
    urllib2.install_opener(opener)

so i guess it is not so difficult to add some api for setting the proxy 
configuration.

if its ok with you, i can contribute

had a quick look and added reading HTTP_PROXY from os env. if you have any 
ideas on
where you want to opener initialized you're welcome to write a patch.

sorry, forgot to close this.

Proxy support is added through the HTTP_PROXY environment variable, set it and 
the 
urllib2 opener gets an proxy handler added. 

Details:
Function pydelicious.build_api_opener accepts extra openers but this argument 
is 
unused within the package. The function itself just adds a HTTPErrorHandler 
instance 
and the proxy handler as described.
Use the extra_handlers argument in your own API initializer modelled after 
pydelicious.dlcs_api_opener, and then override the DeliciousAPI build_opener 
keyword 
with the custom version.

Sorry for re-opening this issue, but you will also need to set the HTTPS proxy 
to make it work behind corporate firewalls/proxies (which is simple):

if HTTP_PROXY:
        extra_handlers += ( urllib2.ProxyHandler( {'http': HTTP_PROXY, 'https': HTTP_PROXY} ), )
