EpicSeqDemo doesn't compile

[BorisHollas]

With epic-2.11 and breeze-2.11, I get

missing or invalid dependency detected while loading class file 'SafeLogging.class'. Could not access term scalalogging in value com.typesafe, because it (or its dependencies) are missing. Check your build definition for missing or conflicting dependencies. (Re-run with -Ylog-classpath to see the problematic classpath.) A full rebuild may help if 'SafeLogging.class' was compiled against an incompatible version of com.typesafe. Epic Unknown Scala Problem

although SafeLogging is shown in the class browser in my Eclipse window.
