reading from mounted volume not working correctly

[stevekm]

For some reason duh is failing to read dirs on a mounted HDD on macOS

./duh /Volumes/Banyan/
Skipping path that could not be read "/Volumes/Banyan/.Trashes": open /Volumes/Banyan/.Trashes: permission denied
Skipping path that could not be read "/Volumes/Banyan/.Trashes": open /Volumes/Banyan/.Trashes: permission denied
Skipping path that could not be read "/Volumes/Banyan/.Trashes": open /Volumes/Banyan/.Trashes: permission denied
10K     /Volumes/Banyan/.DS_Store       |
9.6G    /Volumes/Banyan/.Spotlight-V100 |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
0B      /Volumes/Banyan/.Trashes        |
-----
9.6G    /Volumes/Banyan

need to figure out what is wrong here, its probably a permissions issue in the subdir reader I expect or similar, since it worked fine on a server with NFS mounted.
