How would we build Earth Mark II?

It appears that multiple planets existing in the same orbit is theoretically possible. In that case, how would we go about building a second Earth-sized planet and inserting it into some position in Earth's orbital path? I was thinking planet-construction would be more likely succeed in that region since we know it's a perfect distance from the sun to support life.

Assume we have the technology to supply/harvest, and ship whatever materials required for this endeavor, to whatever location the building takes place. A couple scenarios I've considered:

• Something similar to the world factory in THGTTG, where we build it offsite such that the new planet doesn't mess with other planets' orbits and whatnot. The final product can be transported into orbit later.
• Closer to the Death Star process, where construction takes place in the new world's final orbital location. Seems like this would add complications with gravitational effects on and from other planets, although I'm not sure what exactly.

How plausible are these methods, and what other better ones could work?
