Furthermore, could you please install the libfontconfig1-dev package 
and compile the attached source with "gcc fc-test.c -o fc-test 
-lfontconfig".

It's the relevant part from texttopdf.c copied into a dedicated 
executable. Now please try "./fc-test FreeMono" and tell me the 
results. As this is more or less a re-implementation of "fc-match -s", 
the results should be identical up to the point where a monospaced 
truetype font is found. Can you confirm?
