[Evolution] problem with apt and spidermonkey.helixcode.com

[digger vermont <digger netaxs com>]

Hello,

Recently I've been having problems with updating using apt.  Have the
url's changed?  Here's the lines I have in sources.list: 

http://spidermonkey.helixcode.com/distributions/debian unstable main

http://spidermonkey.helixcode.com/evolution-snapshots/distributions/Debian unstable main

http://spidermonkey.helixcode.com/1.4beta1/distributions/debian/
unstable main

Thanks for the help
