[arch-dev-public] Yet another missing solink announcement

[Antonio Rojas]

The zn_poly package prior to version 0.9.2-2 was missing a soname link. 
This has been fixed in 0.9.2-2, so the upgrade will need to overwrite the 
untracked files created by ldconfig. If you get an error

    zn_poly: /usr/lib/libzn_poly-0.9.so  exists in filesystem

when updating, use

    pacman -Syu --overwrite usr/lib/libzn_poly-0.9.so

to perform the upgrade.
