[ndnSIM] Linking failure during compilng an example under ndnSIM2.1

[Alex Afanasyev]

I would guess that you have multiple versions of boost installed (1.54 and 1.57).  Did you install one of them from source?

I would try removing one and try to recompile everything.  Is it on Ubuntu or some other Linux distribution?  Which exactly version of scenario template (which commit) you're using?
