Google found me your post at Sixapart's forum.
http://forums.sixapart.com/index.php?showtopic=64383Since MT is a paid software, why not contact their support team directly?
I previously had problems with installation and had used full paths in config.cgi and added "BEGIN { $ENV{'MT_HOME'} = /home/blueskyw/public_html/mt/'; }" under use strict line in all cgi files.
Although I have not used MT personally, I would suggest changing the above setting to 'home/blueskyw/public_html/' and see if it works for you.
Edit:
Ok never mind, seems like your search page and the others in the mt/ directory are working. Let me poke around your site and I will take a few more guesses later.
Edit2:
Argh. When did MT became open-source?
