On Arch Linux, Python raises the expected "IsADirectoryError" exception. Perhaps
"PermissionError" is due to a bug in Python 3 on FreeBSD. It would not be the
first exception bug that I have encountered (e.g. os.makedirs(...,
exist_ok=True) raises "FileExists" when permissions differ on existing
directories... very confusing the first time it shows up).

Regardless, svn-export now tries to remove a directory in both cases. Please
updated to version 2013.1.25 and let me know if it works on FreeBSD.

Ok, thanks.

I have changed the time-to-live to 6 months for old archives.
