Hi Richard,

Sorry for the delay in looking at this again.

I can't re-create the behaviour here either, though it was repeatable  
before. However, since then I've made quite a few changes to the  
recipe and done a complete re-build.

It was also failing with the correct paths - I was trying all sorts of  
combinations when the correct one wasn't working!

I'll try and do some more testing here (with what I think the recipe  
was at the time) to see if I can get it to show again. I've only got a  
slow build machine, so it may take a while ;-)
