I have directory information stored in a database that I need to build a report on. Each directory is stored with the complete path (/root/foo/bar/lastdir) and there is a lot of duplication because of this. I would like to be able to sort this data and print it out in a simple easy to read structure (besides the complete path for every item).
Here is the some sample data: 
0555-DDBB/AirPhotos 
0555-DDBB/AirPhotos/AP Labels 
0555-DDBB/AirPhotos/new database 
0555-DDBB/FOO M 
0555-DDBB/FOO M/0555-055-01 Site/Photos 
0555-DDBB/FOO M/0555-055-01 Site/Photos/Digital 
0555-DDBB/FOO M/0555-055-01 Site/Photos/PhotoList 
0555-DDBB/FOO M/0555-055-01 Site/Reports/Summary 
0555-DDBB/FOO M/0555-055-01 Site/Reports/Daily 
0555-DDBB/FOO M/0555-055-02 Design 
0555-DDBB/FOO M/0555-055-02 Design/photo 
0555-DDBB/FOO M/0555-055-02 Design/photo/Ortho 
0555-DDBB/FOO M/0555-055-02 Design/Correspondance 
0555-DDBB/FOO M/0555-055-02 Design/Drafting 
0555-DDBB/FOO M/0555-055-02 Design/Drafting/DWG
I would like to be able to print out a directory structure something like: 
0555-DDBB
  AirPhotos
    AP Labels
    new database
  FOO M
    0555-055-01 Site
      Photos
        Digital
        PhotoList
      Reports
        Summary
        Daily
    0555-055-02 Design
      photo
        Ortho
      Correspondance
      Drafting
        DWG
Basically remove the duplication, and some indenting to show levels ofr the directory tree. But I'm having trouble thinking of a way to store it so I can print it out. I played with some nested hashes, but it seemed to get ugly after I had 6 or 7 levels of directories to sort ($paths{$dir1}{$subdir1} $paths{$dir1}{$subdir2} etc etc). I have each directory in an array and I can split on '/', but from there I'm lost. 

@dirs = ( # list from above );

foreach my $dir (@dirs) {
    my @singleDirs = split(/\//, $dir);

    # stuck
}
