From the B732 QRH (pretty much as stated above, just with a few actual numbers):
PI22.3 Non-Normal Configuration Landing distance (Dry Runway)
Flaps Up (this is the absolute worst case for runway used and approach speed) - the reference distance for a 48 ton landing weight (increasing by 330 ft per 2 tons above this weight, and 440 ft per 1000 above S.L.) is 4750 FEET. George is....what, about 2000m? +- 6700 ft? Approach speed in this case is Vref 40+55. Vref 40 at 48 tons is 132 KIAS.
LE asymmetry or failure is, respectively, 3250 ft reference distance, +170 ft per 2 ton, +180 ft per 1000 above S.L.
TE asymmetry varies, depending on if the flaps are <1 or 1-15, 3950ft, and 3600 ft respectively.
The Flaps up case goes up to 5100 ft with 'good' reported braking action, ie what one could expect with a normal wet runway.
So......why the attempted diversion? Unless I'm missing something, this aircraft should have been able to land at George with ANY flap problem?
All info barring George landing distance available is straight from the B732 QRH.
