gpm 1.20.3-1 in Core

When attempting to update to gpm 1.20.3-1, you will most likely get the following error message:

error: could not prepare transaction
error: failed to commit transaction (conflicting files)
gpm: /usr/lib/libgpm.so.1 exists in filesystem
Errors occurred, no packages were upgraded.

This error arises because the /usr/lib/libgpm.so.1 symlink became disassociated from the package (FS#9949). This is fixed in gpm 1.20.3-1 but its upgrade needs to be forced:
# pacman -Syf gpm
# pacman -Syu
