Multilanguage support

Drupal 7's $language_url global threw me for a loop today. I filed an issue here: http://drupal.org/node/956256 but figured I'd also post something to g.d.o. since issues can be rather hard to find.

While working on a multilingual Drupal 7 site, I loaded the front page and found that the user interface was in one language, while all the links on the page pointed to another language (i.e. different language prefix on all the links).

I could not find anywhere specified for posting support requests? Is there an official place for this?

I am having trouble installing Aegir- I have followed the instructions down to where I am supposed to run install.sh.txt, (sudo su -s /bin/bash aegir -c "sh install.sh.txt") but when I run the comand, I get an error- "Can't open install.sh.txt"

I have double and triple checked to make certain that CHMOD has set the permissions.

If anyone has any ideas, they would be most appreciated!
