+Hi Joey,
+
+Yes, I can work around that particular failure by tweaking constraints.
+
+In particular,
+--allow-newer=\"sandi:base\" --allow-newer=\"aws:time\"
+
+I also first need to \"cabal install Cabal<1.25\" because git-annex seems
+to have a compatibility problem with Cabal-2.0.0.2. The error with
+Cabal-2.0.0.2 is
+
+[[!format sh \"\"\"
+Building executable 'git-annex' for git-annex-6.20170520..
+
+Build/BuildVersion.hs:1:1: error:
+    File name does not match module name:
+    Saw: ‘Main’
+    Expected: ‘Build.BuildVersion’

+git-annex-6.20170520-3mbb3kAWTlXI0EMervIo66 failed during the building phase.
+The exception was:
+ExitFailure 1
+\"\"\"]]
+
+But, once I've installed the lower version of Cabal, and tweaked the 
+constraints for sandi and for aws, git-annex does build successfully.
+
+However, at that point a more serious issue comes up when I run \"git 
+annex test\" and here is the full log:

+Here is a snippet:
