From what I can understand right now layman uses svn to pull the portage overlay for sabayon. If I'm wrong please correct me. However if this is the case is there any way to have it use port 80 for webdav? My company uses a very restrictive firewall and proxy that doesn't even allow DNS request unless you go through it's ISA server. I have ntlmaps set up which sets up a localhost proxy through the ISA for things such as portage (since normal proxy doesn't understand DOMAIN\username syntax).
If layman doesn't use svn, then how can I tell it to use my proxy settings? Portage works fine as I've got the proxy set up, but layman doesn't, which tells me it isn't using the proxy evironment variables.
