[racket] Missing entries for DrRacket Menu items

I had Racket 6.0 on my Mac.  I then installed the package drracket-vim-tool.

$ pwd
/Applications/Racket v6.0/bin
$ ./raco pkg install ~/Downloads/drracket-vim-tool

It installed fine and the Vi mode was there.  I tried it out and it seem 
to work ok.  Then I noticed that for the DrRacket Menu selection for 
Edit->Modes and Edit->Keybindings, there weren't any choices any more.  
I am not sure what happened.  I then unistalled the pkg.

$ ./raco pkg remove drracket-vim-tool

That did not help, the entries were still missing.  I uninstalled 
DrRacket6.0 with AppCleaner and then emptied the trash.  Then I 
reinstalled DrRacket6.0 and the entries were there again.  When I 
installed the drracket-vim-tool pkg again, then the entries 
disappeared.  I deleted drracket-vim-tool and I then deleted Racket6.0 
and installed it again, but the entries were still missing.  I did not 
install the drracket-vim-tool package again.  I repeated the process of 
uninstalling and installing Racket6.0 a few more times with the same 
result.  I uninstalled Racket6.0 and then installed Racket6.0.1.  Same 
thing.  I also delete a few racket related items that I found in 
/Library and ~/Library during the times that I uninstalled Racket.

I am not sure if there were anything else missing from the Menus, I just 
noticed those two in Edit since I was in there.

Any ideas?

Thanks.
