What happens then if also the second item on the list cannot be build
because you lack a tech. Wouldn't the result be an infinite loop?

I would suggest that whenver you want to build something from the list
that you search the list for the first item that you CAN build and then
move it to the top. 
This would ofcourse generate an error if there is no items that you can
build.
