Cannot delete dav/activities.d when removing SVN repo



Have been rearranging my SVN repositories of late and ran into a small problem deleting an old one after removing it from the Web Panel.

rm nameOfRepo/ -rf
rm: cannot remove directory `nameOfRepo/dav/activities.d’: Permission denied

stat reports that activities.d has:
Access: (0755/drwxr-xr-x) Uid: ( 999/dhapache) Gid: ( 150/dhapache)

this was an empty repo infact, one that I hadn’t actually used - and I was able to successfully delete another just after this.

Any ideas? Guess I need to ask DH directly to nix that dir?
