[PLUG] Ubuntu 10.04 and missing links

[website reader]

Has anyone else noticed this, or is it just my system?  I am running a
64 bit version of Ubuntu 10.04 lucid edition of linux.  Today I
happened to use the recursive grep command on the /usr folder, and to
my surprise I noticed a lot of "No such file or directory" messages.

Investigating further, I found over 10,530 such messages when
searching the whole /usr folder and all of these pertained to symbolic
links that pointed to missing files.

I also saw this on the latest 11.10 oneiric edition of Ubuntu also, in
the /usr area, on another machine that I have.

I am puzzled that over 10K symbolic links go nowhere.

Of course, I am afraid to touch anything, but still 10,540+ messages
seems a lot to me.

Your thoughts?  Is this something that needs to be addressed?  Could
this have been something overlooked?
