Spiders and Link Structure on site that is being built

What is the best time to start link building for my site.

I am in the process of building a new site.

It is a site with a dozen categories and in each category there are about a dozen pages of content for that category.

I know exactly what these content pages are going to be about and have temporarly linked them to the index of the site until I have them developed.

As I develop these pages, I link them to the correct place but my question is this:

Would it be a mistake to start promoting this site so that it can start getting some SERPS for the pages that I already have developed? Would google and other search engines not like the fact that there are a lot of links that go to the index although later they will be linked to their own pages?

I hope I've explained this in a way that is understandable. I'm just trying to figure out if promoting a site before it's finished with a lot of links that are going to be changed is ok as compared to starting to link build and promote once the site is totally complete.

Any incite greatly appreciated. :)

Hello filo. I've had better luck using stub pages with a summary of what is to come.
