Package: tkgate Version: tkgate-1.8.7-1 When you run tkgate and start the simulation it says it cannot find gsim in /usr/share/tkgate/libexec/ and apt-file lists location for gsim as /usr/bin/gsim. If you try to do anything in the simulation like flip a switch the application crashes with the command line output ob_error: ob_end_frame with no matching ob_begin_frame()Aborted.
Adding a symlink between the real binary and where the application expects gsim corrects the problem.
