"prt-get" does not install anything

"prt-get depins package" fails. it fails only when it tries to connect to "dl.sourceforge.net" ro doownload source packages. when i tried to open that address in Firefox i get this page: http://mir1.ovh.net/ "prt-get" hangs in there like this: dl.sourceforge.net | 80 and then does not do anything. i am not able to install most of the packages i need, like "alsa" "mpg321", "emacs" etc. any solution ? -- http://arnuld.blogspot.com/
