OK, this one is certainly hitting everyone.  It is number 1 on the
what's new about swarm 2.0 in the FAQ.  The executable "VotingModel" is
not the executable anymore.  Open it with an editor, it is a script that
activates the real executable, which is in a hidden directory .libs.  SO
to use gdb  you do this

gdb .libs/VotingModel.

and in emacs. instead of telling it the executable is VotingModel, use
.libs./VotingModel
