The nutrition consultant skin is a 1 column skin. It would have to be changed to a 3 column skin in artisteer to work properly in mojoPortal. You don't have to use 3 columns, it just needs to be 3 columns capable.
All artisteer skins that I use (about a dozen) all have a jquery.js file in the skin folder.
Some artisteer skins work fine as-is in mojoPortal, But all those that I have chosen lately require me to re-order some of the tag sections in my layout.master file. If this is required for yours, you have to make the layout.master tags order match the tags order of the index.html generated by artisteer. It usually takes me about 10 minutes to do this now although the first one probably took me 30 minutes. It can be done having both files opened in text editors, but file compare editors work better. If you have never done this before, you need to wrap your head around how markup tag nesting works. There is an open and a close tag, etc...
Hope this helps
