Ah, you didn't show that part of the 'make' output.  'make check' should 
succeed, and does succeed on my platform (Fedora 21 x86-64). What 
platform are you running on?

Suppose you manually edit tests/Makefile, by removing the "@" from the 
triple-backref.log line, as follows.

What is the relevant part of the output of "make check" then? Here's 
what it looks like for me:

...
