commit fails with "has no ancestry information" error

If I try to perform the following command:

% svn commit -m ''

I get the following error:

svn: '/d0/home/tlm/path_to_some_dir/Project' has no ancestry information

FWIW, the directory where I'm carrying out this command is

/d0/home/tlm/path_to_some_dir/Project/dist

which was generated by executing the command

% svn checkout file:///d0/home/tlm/path_to_my_repo/Project/trunk dist

while in the directory /d0/home/tlm/path_to_some_dir/Project.

What does the error mean, and how can I fix whatever it's causing it?

Thanks!
