This suggests a possible workaround by manually installing a more recent version of libbsapi, altough its license isn't free and the library distributed is 32-bit only: http://volker.de/2012/12/fingerprint-gui-und-das-thinkpad-t430s/
This suggests a free library may become available in the near future.
