I just got everything running on a different m/c, with plib, 
SimGear & FlightGear compiled from the same cvs state as the m/c 
with the problem and the latest 3d clouds work ok.

It looks like the problem is due to the graphics card & drivers.

The system that has the problem is fitted with an ATI 9200 256MB 
card and I've had to use some drivers that I got via the 
developers of the 3d s/w I use for their s/w to work correctly 
(apparently there was a problem with GL threading in the 
standard drivers).  As it took quite a lot of effort to get it 
running and stable I've been reluctant to update so it's still 
using pretty old s/w, albeit with current cvs stuff.

The system that works ok is fitted with a new nVidia 6600 256MB 
card that I've just got to replace the ATI one.

Once I've replaced the ATI card on my main system I'll put it in 
a backup W/S as it'll be less critical to run the 3d modeller on 
it and I can afford to mess about with it more.
