ports/159335: [Patch] Update games/klavaro to version 1.9.3

[Herbert J. Skuhra]

Hi Tilman,

at the moment I cannot reproduce this build error on my systems.

A few minutes ago I successfully built the port on another machine:
FreeBSD 9.0-CURRENT amd64 (r224307).

Is x11-toolkits/gtkdatabox (fully) installed?
Do you have '/usr/local/include/gtkdatabox/gtkdatabox.h'?
Can you successfully build the port at version 1.9.1?
