squid 2.2.STABLE4 in a chroot environment

Hey squid users!

I have installed a few days ago squid (Squid Cache: Version 2.2.STABLE4) for the
 first time on a
Linux 2.2.5 into the default install directory (/usr/local/squid). Squid worked
immediately as expected.

But because my real intention was to run squid in a chroot environment I
continued with the following
(listed as exactly as I can remember the scenario...):

1) mkdir -p /usr/local/anywhere/jail (in the continuing progression this should
be our new root)
2) mkdir -p /usr/local/anywhere/jail/usr/local
3) mkdir -p /usr/local/anywhere/jail/etc
4) I didn't know which files are the important ones therfore I copied all /etc
contents to the
     /usr/local/anywhere/jail/etc
   I have done the same procedure with the files in the /lib path (the commands
in the /bin section are
   dynamic executables) and with some files (bash, date, expr, sh, sleep) needed
 by the script RunCache.

5) cd /usr/src/squid2/squid-2.2.STABLE4
6) su squid
7) ./configure
8) Modified in ./src/Makefile the entry
     LDFLAGS = -g -static

9) make all
10) make install
11) cd /usr/local/squid
12) Modified some entries in the squid.conf file among these
     cache_dir /usr/local/anywhere/jail/var/squid/cache 900 16 256
     cache_effective_user squid
     cache_effective_group nogroup

13) squid -z

At this stage squid is working!

After...
     cd /usr/local
     mv ./squid/ /usr/local/anywhere/jail/usr/local/
     cd /usr/local/anywhere/jail/usr/local/
     modifying in squid.conf the entry
          cache_dir /var/squid/cache 900 16 256

     switching to user root (only root can perform the chroot command)
     chroot /usr/local/anywhere/jail /usr/local/squid/bin/RunCache

...I got the following cache.log:

Sorry for the long explanation and thank you in advance for any constructive
comment!
