Thanks for the pointer. I think I've fixed the immediate problem.

But I got such sandbox violations when emerging packages from the main 
portage tree more than once. Many packages use LaTeX for documentation; 
metafont can be called at any moment. Shouldn't the directories to which 
it writes generated fonts be added to SANDBOX_WRITE globally? Then the 
level of users' frustration would be lower.
