With a system that has not been updated for over 3 years, I would suggest to 
Start from scratch and copy the config across.

If you do insist on trying to work through this, I would suggest the following 
(READ and understand all steps before executing any):

0) Make sure you do NOT change your profile. (As you adjusted it from 13.0 to 
17.1, change it back to 13.0, or if not available, 17.0)
- Profile 17.1 is NOT going to work at this point.


1) Rename the world and world_sets files to (temporarily) clear the entire 
world-set
(These files are located in "/var/lib/portage")


2) execute: "emerge -vauDN --with-bdeps=y --backtrack=200 @world" and 
alternate with "emerge --update --newuse --deep @world" until both have 
nothing left to do.

3) execute "emerge -va --depclean"
- This is a LARGE set, don't worry, it will all come back (You DID backup the 
files in step 1, right?)

4) Fix any config-file changes that are left over and follow this with steps 
"2", "3" and "4" until your system is clean.

5) Install, configure and compile the kernel and ensure you can reboot the 
system. (This is important for the next step)

6) Follow the news-item regarding migrating to 17.1 and follow this exactly. 
(Your install is extremely basic, so it should be nice and easy)

7) Reinstall all needed software (read your world and world_set backup-files 
to see what you had before and ONLY install those that you actually need)

8) Fix any config-files that are needed for the software you re-installed in 
step 7

9) Congratulate yourself for managing to upgrade a system after 3+ years


In my experience, when the system has not been updated for this long, the 
fastest way to resolve this is to start from scratch with a backup of any 
config and data files.
