There's an extra backslash at the end of the server name (before the folders start). It'd look similar to http://foo.com//folder/to/get/from/... It errored when it tried to retrieve the file and went to ibiblio.org (which worked). I'd downloaded my ISO that I started with from them...not sure if it was somehow encoded on the CD to contact that address or what.
Portage, as in sys-apps/portage, or portage as in 'emerge-webrsync' or is it some other "portage" you're refering to? What command did you use? emerge -V (if relevent)
