If I make the class the following, i can get it to work:
class PrintFunctionsConsumer : public ASTConsumer, public 
RecursiveASTVisitor<PrintFunctionsConsumer> {
public:
   bool VisitCallExpr (CallExpr *E) {
     llvm::errs() << "Function call maybe?!";
     return true;
   }
   virtual void HandleTranslationUnit(ASTContext &ctx) {
     TraverseDecl(ctx.getTranslationUnitDecl());
   }
};
