Are you root?

$ ls -l /proc/1/exe
ls: cannot read symbolic link /proc/1/exe: Permission denied
lrwxrwxrwx 1 root root 0 2008-12-23 07:30 /proc/1/exe

# ls -l /proc/1/exe
lrwxrwxrwx 1 root root 0 2008-12-23 07:30 /proc/1/exe -> /sbin/init

You'll probably find that it will work if the process you are trying to 
look at is owned by yourself or if you are root. I think that what the 
error message is telling you is that it can see the symlink but can't 
follow it.
