Maybe the following is of any help, I was confused by the TestWriter etc. passing in my local checkout, but not when I later tried to build gdcm from the real guix repository. This can be reproduced as follows: 1. Check out and build the original commit to add gdcm 2.8.9 (15caeb745c) 2. Check out and build the "upgrade to 3.0.20" commit (2bdbd962e3) Now the tests suddenly pass. What does the build of 2.8.9 leave behind? I'm still really confused by this! -- Mvh, Tor-björn Claesson
