In the past months I've tried ccache in poudriere, but I also got random 
permission errors like you. Running poudriere bulk again completed 
without error, even though I didn't change anything in the poudriere 
configuration. After 4 or 5 months with ccache enabled, I turned it off.
It only brought me more trouble.
