Narrative:

Shortly after gear retraction we got a gear disagree message and the right-hand landing gear light indicated down and locked. There was also a light vibration coming from the landing gear area. We asked [ATC] for vectors and eventually holding; which was assigned at 7;000 ft. While the first officer and I worked the problem using the QRH; the relief pilot/check airman communicated with dispatch. Then I spoke to maintenance control and asked about lowering the landing gear. After some prodding he confirmed our problem was with the gear up portion of the system; not the gear down part. Following some discussion in the cockpit; we lowered the gear and got three green. We now declared an emergency and advised ATC that we would require the 'equipment upon our landing'. I extended the speedbrakes to expedite fuel burn. We left holding weighing 280;000 pounds and landed uneventfully. [We had a] mechanical failure of the right-hand gear retraction mechanism. I found the gear disagree checklist somewhat confusing. It goes from step 1 to step 4 seemingly bypassing the gear down part.
