It lloks like you have NOT a sane chroot enviroment... remember, you cannot 
access a socket in /tmp when chrootet to /jail  - it has to be 
/jail/tmp/socketfile as an example...
Check the availability of the offending libraries as the chrootet user your 
running apache with, make a su and chroot to /jail and test it one by one.

If all is sane, a script which checks and compares this environment with 
global system files is extremely helpful when upgrading the system...
