I don't think this is a chkrootkit problem. Just running "find" (as root) on 
my RaQ 4 generates the same error:

[root /root]# find / -name "foobar.txt" -print
find: /proc/5/fd: Permission denied

[root /root]# ls -alF /proc/5/fd
ls: /proc/5/fd: Permission denied

[root /root]# ls -alF /proc/5

Just for ha-has I took a look at /proc/4. I have no idea if they should be the 
same or not, but here's what I got:

[root /root]# ls -alF /proc/4
ls: /proc/4/exe: No such file or directory

And another FWIW - on my Fedora machine, I don't get the "permission denied" 
problem:

[root@localhost root]# find / -name "foobar.txt" -print
[root@localhost root]# ls -alF /proc/5/fd
