What I did is:
* On my build host, I compiled the full system and creating packages
* On the client (i.e. The machine in question) I simply did a emerge -auvDNk 
world.
* Portage did not complain about any conflicts, the amount of packages is what 
I expected, so I started the upgrade.
* After about 25 packages installed successfully, emerge stopped with the 
errors explained before.

For me the problem is solved now as I could recover the system, but I still 
would like to know how to prevent this -- installing glibc prior world may be 
a good idea.
