Yes.  You have several options:
1. As you noticed you can turn off chroot.
2. You can turn off delayed resolver (to resolve hosts at startup, before 
chroot).
3. You can create the files/devices your resolver library needs inside the 
chroot jail.
    strace is your friend: http://sourceforge.net/projects/strace/
4. You can use IP address as "connect" parameter instead of domain name.
