Hi ARaspiK,
Thank you for your detailed description of the symptons. Would you
please create a bug report[1] to better track the issues?

The best way to move forward is to prefixify it. You will need to study
the source code of sys-apps/shadow, and figure out the code that reads
/etc/passwd and /etc/group to come up with a patch.

This might work but is not encouraged.

They are written automatically by gcc of the Prefix. Actually, the
binaries compiled from sys-apps/shadow have their libraries
prefixified.
